An oval, white "eyespot" is just above and slightly behind each eye. They have teeth that can be as long as 4 inches. The population of Southern Resident killer whales in the Pacific Northwest is one of the most critically endangered marine mammals. This separation of the ear bone complex allows a killer whale to localize sound (directional capacity), which is important for echolocation. Killer whale is the largest of the dolphin family and also the strongest and powerful predators. Human speech falls within the frequency band of 100 to 10,000 Hz (0.1 to 10 kHz), with the main, useful voice frequencies within 300 to 3,400 Hz (0.3 to 3.4 kHz). The pectoral flippers of male killer whales are proportionately larger than those of females. A killer whale breathes through its blowhole. A killer whale does not chew its food — instead its teeth are adapted to grasp prey and tear its food into smaller chunks. The killer whale has a sleek, streamlined body. Both types have a dorsal saddle, a dorsal cape (dark gray covering on the back), and can have a yellowish cast due to a layer of diatoms on their skin. The skin is very smooth to avoid friction from the water as they swim. The way they use their ability to "taste" is unclear. A killer whale's eyes are about the same size as the eyes of a cow. Crazy about roller coasters? Killer whales can survive in the cold polar regions of Antarctica and the Arctic Circle, as well as the warm waters of the equatorial regions. This is because prey animals may try to injure their eyes in order to escape, but the obvious false eyespot may draw attention away from the real eyes. In fact, the orca is the biggest member of this group. Killer whales have a well-developed, acute sense for hearing underwater. The dorsal saddle does not contain any black areas. Adult offshore killer whales in the Northeast Pacific also have highly worn teeth, likely caused by a diet that includes sharks with highly abrasive skin. The five forms of Antarctic killer whales look different and are easier to tell apart. A killer whale has an indistinct rostrum (snout-like projection). Early studies published in 1972 suggested that the hearing range of killer whales was about 0.5 to 31 kHz. Type 1 killer whales are much smaller than type 2. Extensive wear has been noted on the teeth of older individuals. Eyesight. It is not fully understood why wild killer whale populations develop abnormal dorsal fins or why the observed killer whale males around New Zealand had such a high rate of dorsal fin abnormalities compared to other studied populations. Above the pods in the social structure are clans. Find a variety of free classroom activities that will keep your students engaged and excited to learn about animals. Adult male killer whales are larger overall than their female counterpart including features such as pectoral flippers, dorsal fins, tail flukes, and girth. Pitman RL, Durban JW, Greenfelder M, Guinet C, Jorgensen M, Olson PA, Plana J, Tixier P, Towers JR (2011) Observations of a distinctive morphotype of killer whale (Orcinus orca), type D, from subantarctic waters. The ventral (bottom) surface, lower jaw, and undersides of the tail flukes are mostly white. The teeth of killer whales begin to erupt from several to 11 weeks of age, which corresponds with the time that calves are seen taking solid food from their mothers. Browse our extensive collection of zoological career infobooks including animal training, animal rescue and rehabilitation and zoo careers. Find a variety of free classroom activities that will keep your students engaged and excited to learn about animals. These small external ear openings lead to reduced ear canals that are not connected to the middle ears. The dorsal surface and pectoral flippers are black except for a grayish patch (saddle) that lies behind the dorsal fin and a white eyespot … Blood circulation in the pectoral flippers adjusts to help maintain body temperature. While extremely rare, white killer whales have been observed. At least in bright light, constricting the pupil helps, but it doesn't fully explain how a whale achieves visual acuity in air. Hear animal sounds for animals like anteaters, dolphins, frogs and more. Killer Whale Living Relationships . In killer whales, the ear bone complex (ootic capsule) isn't attached to the skull. Are you wild about whales? Blubber is fat that keeps the killer whale warm. Find quick information and fun facts with these 1-page easy resources about animals from A to Z. DNA analysis of several other species of toothed whales indicated that the eyes of these whales do not develop pigment cells called short-wave-sensitive (S-) cones, which are sensitive to blue light. Greatest sensitivity ranged from 18 to 42 kHz with the least sensitivity to frequencies from 60 to 120 kHz. Type A killer whales have a medium-size, horizontal eye patch and have a very faint dorsal saddle. Of the groups of killer whales studied, researchers have learned to recognize many individual killer whales from photographs, especially photos of the dorsal fin and saddle patch. A 3-4 week clerkship for veterinary students wanting to augment their knowledge and experience in non-domestic animal medicine. Male Antarctic type A killer whales can reach lengths of 9.2 m (30 ft.) making them the largest known killer whales. In particular, fat lobes in the whale's lower jaw appear to be an adaptation for conveying sound to the ears.

Fast killer whale facts. The entire dorsal (top) surface and pectoral flippers are black except for the gray saddle. Experts note subtle differences between the resident, transient, and offshore killer whales of the eastern North Pacific Ocean. A killer whales uses its rounded, paddlelike pectoral flippers to steer and, with the help of the flukes, to stop. Blubber is a layer of fat reinforced by collagen and elastic fibers. Flukes are flat pads of tough, dense, fibrous connective tissue, completely without bone or cartilage. At SeaWorld, average size for females is 5.5 m (18 ft.) and 2,442 kg. To open its blowhole, a killer whale contracts the muscular flap. Crazy about roller coasters? Three studies indicated that taste buds may be found within 5 to 8 pits at the back of the tongue. In the eye of a land mammal, the cornea focuses light rays toward the lens, which further focuses the light rays onto the retina. So are we! Scientists are undecided whether dolphins have taste buds like other mammals. Some scientists also believe that the eye-spots might help other orca recognize body orientation in dark or murky water. Researchers identify individuals using many features including dorsal fin shape, nicks in the dorsal fin, relative body size, pigmentation patterns of saddle patches and eye patches, scars, deformities, detail of tail fluke edges, encrustations, blemishes, and rake marks. A 3-4 week clerkship for veterinary students wanting to augment their knowledge and experience in non-domestic animal medicine. Being air-breathing animals that spend a majority of their time under water, … while an adult female killer whale will grow to an average length of 16 – 23 ft. long and weigh between 3,000 lbs. The orca, also called a killer whale, is a type of toothed whale. Since children have a similar cognitive development as most animals, animals likely think the eyespot is the orca's real eye too. To open its blowhole, a killer whale contracts the muscular flap. The strongly convex (spherical) lens of a marine mammal differs from that of a land mammal. Taken with tigers? An oval, white “eyespot” is just above and slightly behind each eye. Body Shape. In this rare event, a pod of killer whales hunt and kill a large fin whale.

In general, blubber has a number of important functions: A killer whale's dermis (skin) is smooth. Environmental reason a What ever environmental change that produced the barrier from ANTH 760 at San Francisco State University Although killer whales have 50 to 54 vertebrae, no bones extend into the flukes. Being air-breathing mammals that spend a majority of time under water, a sense of smell would go largely unused in killer whales. In air, a marine mammal's eye compensates for the added refraction at the air-cornea interface. Learn about our work to protect and conserve this species. The skeletal elements are rigidly supported by connective tissue. Polar Biol 34:303–306 They're immediately recognizable by their distinctive black-and-white coloring.

Researcher theories include these observed abnormalities may be attributed to age, stress, and/or attacks from other killer whales. They have very distinct white eye patches and a conspicuous saddle. Killer whales are black and white, with a gray patch called a "saddle" or a "cape" on the back, just behind the dorsal fin. Killer whales use 40 four-inch long teeth to capture prey such as tuna, seals, squid, and penguins. Transient killer whales tend to be smaller and have a more pointed dorsal fin. Within the pods, there are smaller units called maternal groups, consisting of mothers and their offspring. The people of SeaWorld Parks & Entertainment are truly and deeply driven to inspire on behalf of, to celebrate and connect with, and to care for the natural world we all share. The killer whale is easy to identify by its size and its striking coloration: jet black on top and pure white below with a white patch behind each eye, another extending up each flank, and a variable “saddle patch” just behind the dorsal fin. Studies of closely related species (common dolphins, bottlenose dolphins, and false killer whales) suggest that the most sensitive areas are the blowhole region and areas around the eyes and mouth. Our overarching zoological mission is to foster conservation awareness and to impart action on our park guests to preserve wild animals and wild places. (5,384 lbs.) In between the dorsal fin and the peduncle is a grey swoosh known as the saddle patch. short bursts: 45 km/h typical traveling speed: 6-8 km/h Dreams About Killer Whales – Meaning and Interpretation.

Conspicuous eye and saddle patches may help killer whales in groups coordinate social interactions, hunting, and swimming in formation. long and about 2.5 cm (1 in.) Researchers theorize that all modern cetaceans, including killer whales, lack these visual pigments and therefore aren't able to discriminate color in the blue wavelengths. The size and shape of a killer whale's white areas and gray saddle vary greatly among ecotypes. © 2021 SeaWorld Parks & Entertainment, Inc. All Rights Reserved. Olfactory lobes of the brain and olfactory nerves are absent in all toothed whales, indicating that they have no sense of smell. Conspicuous eye and saddle patches may help killer whales in groups coordinate social interactions, hunting, and swimming in formation. The outer layer continually and rapidly renews itself, and the old skin sloughs off. Despite their name, killer whales … A killer whale's brain and nervous system appear physiologically able to process sounds at much higher speeds than humans, most likely because of their echolocation abilities. The killer whale’s current population range is about 50,000 and they are the most distributed marine mammals. Please go to your browser preferences and enable Javascript in order to use Scratch. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. Others appear to be full-grown adults and the cause of their white coloration is unknown. Another study could not trace a nerve supply to the taste buds. In the flickering, filtered sunlight of the sea, other animals may not recognize a killer whale as a potential predator. The strongly convex (spherical) lens of a marine mammal differs from that of a land mammal. The blowhole is relaxed in a closed position, and the flap provides a water-tight seal. Killer whales, or orcas, have the second-biggest brains among all ocean mammals, weighing as much as 15 pounds. Contributing to a killer whale's streamlined shape, which helps increase swimming efficiency, Storing fat, which provides energy when food is in short supply, Reducing heat loss, which is important for thermoregulation.

More recent studies show killer whales could hear sounds at frequencies as high as 120 kHz. A large male killer whale may have tail flukes measuring 2.75 m (9 ft.) from tip to tip. Compared to other body shapes, this body shape creates less drag (the opposing force an object generates as it travels through water). Take a deep breath, gang – because we’re diving to the depths of the ocean with some cool killer whale facts!. Pods are long-term units made up of males, females, and calves. By Hannah Osborne On 3/11/19 at 9:48 AM EDT. in diameter. Type 2 killer whales are one of the largest ecotypes, with males reaching 8.5 m (29 ft.) lengths. Soft tissue and bone conduct sound to a toothed whale's middle and inner ears. There are two types of saddle patches: open, which has more black in it: and closed, which has more white. Large type B killer whales have a very large, horizontal eye patch. Teeth are about 7.6 cm (3 in.) Ears are small inconspicuous dimples just behind each eye, with no external flaps or pinnae. The general body shape of a killer whale is roughly cylindrical but tapering at both ends. The ventral surface, lower jaw and undersides of the flukes are predominately bright white. Data from Icelandic killer whales (North Atlantic type 1) indicate that an average-size male is about 5.8 to 6.7 m (19 to 22 ft.) long, while females averaged 4.9 to 5.8 m (16 to 19 ft.) long. The white spot on each of the eyes is called the eyespot. As in the flukes and the flippers, arteries in the dorsal fin are surrounded by veins to help maintain body temperature. In zoological parks, killer whales show strong preferences for specific types of fishes. Killer whales in the Eastern Tropical Pacific tend to have barnacles (Xenobalanus spp.) Learn more about the Seasonal Camp Counselor program at SeaWorld. About 4.7% of wild adult male killer whales around British Columbia were observed with dorsal fin abnormalities. There are usually 10 to 14 teeth on each side of each jaw (40 to 56 teeth total). The increased skin cell turnover increases swimming efficiency by creating a smooth body surface which reduces drag. Like the keel of a boat, the dorsal fin may help stabilize a killer whale as it swims at high speeds, but a fin is not essential to a whale's balance. In most females, the dorsal fin is slightly falcate (backward-curving) and smaller — about 0.9 to 1.2 m (3 to 4 ft.) tall. Due to their high intelligence and ability to be trained, they are often stars … “Iceberg” is the only completely white (albino) killer whale known to exist. Researchers photograph the dorsal fin when the whale rises out of the water to breathe. The distinctive coloration of killer whales is a type of disruptive coloration, a camouflage in which the color pattern of an animal contradicts the animal’s body shape. A killer whale's forelimbs are adapted for swimming. Most adult North Atlantic type 1 killer whales have severely, worn-down teeth, which is consistent with a diet of suctioning up small fishes. The Orca has the name killer whale because they can take down any large creature such as seals, sea lion or even white shark. This mainly falls within a killer whale's hearing range.

A killer whale's eyes are about the same size as the eyes of a cow. Like the flukes, the dorsal fin is made of dense, fibrous connective tissue, without bones or cartilage. A single blowhole on top of the head is covered by a muscular flap. The largest recorded male killer whale was 9.8 m (32 ft.) in length and weighed 10,000 kg (22,000 lbs.) A fusiform body shape has less drag, which means that it is an efficient swimmer. This characteristic fusiform shape is quite energy efficient for swimming. Underwater, the cornea isn't able to adequately focus waves into the lens because the refractive index of water is similar to that of the interior of the eye. The most popular theory is that orca eye-spots protect their actual eyes by providing a false target (prey animals will often attack the eyes of their predators). Pectoral flippers have the major skeletal elements of the forelimbs of land mammals, but they are shortened and modified. Each lobe of the two-lobed tail is called a fluke. Type D killer whales have an extremely, tiny eye patch, a bulbous melon (forehead), and a very faint saddle. Scientific name: Orcinus orca Family name: Delphinidae Classification: Mammal IUCN status: Data deficient Lifespan (in wild): 50 … Glands at the inner corners of the eye sockets secrete an oily, jellylike mucus that lubricates the eyes, washes away debris, and probably helps streamline the eyes as a killer whale swims. The people of SeaWorld Parks & Entertainment are truly and deeply driven to inspire on behalf of, to celebrate and connect with, and to care for the natural world we all share. These are the smallest type of killer whale. When viewed from below, the lighter belly surface blends in with the brighter sea surface. A killer whale's eyes are on each side of its head, just behind and above the corner of its mouth, and in front of its white eyespot. In British Columbia, one such animal was diagnosed with Chédiak-Higashi Syndrome, an inherited fatal disorder characterized by loss of pigmentation and not surviving to adulthood. Type C killer whales have a small, forward-slanting eye patch and a dorsal saddle and often have a yellowish cast due to a covering of diatoms. In comparison, the range of hearing of a young, healthy human is 15 to 20,000 Hz (0.015 to 20 kHz). Go behind-the-scenes to see how our trainers care for and interact with these amazing animals, and get up close with some finned, flippered, or feathered friends. Reaching a height of up to 1.8 m (6 ft.) in a large adult male, it is the tallest dorsal fin of all cetaceans. The killer whale (Orcinus orca), also known as the orca, is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Offshore killer whales are more similar in appearance to the resident ecotype, although they are smaller than either the residents or transients and they have a faint saddle. Some of the others include the Pygmy Killer Whale, False Killer Whale, and the Melon-headed Whale. This action exposes the most markings on the back and dorsal fin. The killer whale is the largest member of the dolphin family. In the eye of a land mammal, the cornea focuses light rays toward the lens, which further focuses the light rays onto the retina. A white “eyespot” is located just above and slightly behind each eye and a gray saddle is located behind the dorsal fin. Toothed whales have only one set of teeth; they are not replaced once lost. The coloring varies depending on where the Orca lives. Come face-to-face with the wonders of wildlife through species-focused episodes and related classroom activities. The undersides of the tail flukes are fringed with black. attached to the back edge of their dorsal fins. They Are Very Intelligent. The size and shape of a killer whale’s white areas and gray saddle vary greatly among ecotypes. Adult male killer whales are larger overall than their female counterparts. SeaWorld's adult female whales range in weight from 2,313 kg (5,100 lbs.) The coloring varies depending on where the Orca lives. Come face-to-face with the wonders of wildlife through species-focused episodes and related classroom activities. In general, resident killer whales are larger and have a rounded tip on the dorsal fin, which is falcate (curved back) in adult females and tall and triangular in males. The underside of the body and underside of flukes are white and there is a white eyespot behind each eye. Behavioral evidence suggests that bottlenose dolphins, a closely related species, can detect three if not all four primary tastes. ... Respiration. Killer whales are countershaded: the dorsal (top) surface is darker than the ventral (underneath) surface. Overall, however, little is known about a whale's sense of taste. In adult males, the dorsal fin is tall and triangular. thick. This may occur in male or female dorsal fins. The eye of a marine mammal compensates for this lack of refraction at the cornea interface by having a more strongly spherical lens. Tech & Science Orca. Regardless, behavioral studies indicate bottlenose dolphins have some type of chemosensory capacity within the mouth. When viewed from above, a countershaded animal blends in with the darker ocean depths. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. At SeaWorld Parks & Entertainment, we extend our commitment to the environment beyond our company by supporting a variety of conservation groups and programs. But of the adult male killer whales that have been photo-identified in the waters around New Zealand, 23% (7 out of 30) had collapsing or bent dorsal fins. A killer whale's large teeth are conical and interlocking. Above are historic field images used in killer whale photo identification. OpenLink Faceted Browser; OpenLink Structured Data Editor
