Norway to the tip of South Africa Distribution In the Northwest Atlantic, this species has separate inshore and offshore distributions: Inshore occurs within about 5 miles 7. Physical Characteristics Generally slate gray to charcoal in color, including counter shading darker dorsally and lighter ventrally. Sides of the body often have light brush markings.
A streamlined body propelled by powerful tail flukes exceptionally equips the bottlenose dolphin to dive deep or swim swiftly. It can reach speeds of 22 miles per hour 35 kphand its cruising speed of 5 miles per hour 8 kph keeps pace with the fastest human swimmers.
Dolphins engage with their environment through sound. An apparent cacophony of clicks, squeaks, and whistles helps individuals identify and communicate with one another. Due to peg-like teeth and weak chewing muscles, dolphins devour their prey whole; one bottlenose dolphin may consume 32 pounds Bottlenose dolphin society can be as fluid as their marine environment, with relationships among individuals repeatedly forming and fissioning.
Populations in the eastern Pacific and North Atlantic also occur in two physically, genetically, and behaviorally distinct coastal and offshore forms. These coastal and offshore populations do not overlap or interbreed and could become—or already be--separate species.
Coastal dolphins can be spotted from beaches, bluffs, or boats. The offshore form is infrequently seen as its members stay seaward of the continental shelf. Bottlenose dolphins move seasonally between the Southern California Bight and Monterey Bay, but they had been relatively rare around Monterey Bay before following warmer water and extending their range northward in the early s.
Conservation At one time as many as 8, common dolphins perAround one million bottlenose dolphins may exist worldwide. Bottlenose dolphins are the most commonly captured cetacean for sea parks and other purposes of public display.
Live-animal capture continues in several parts of the species' range, including the tropical Pacific and the Black Sea. Bottlenose dolphins are caught intentionally in harpoon and drive fisheries for human consumption or use as shark bait, but incidental bycatch in bottom-set gillnets and purse-seine nets poses a bigger conservation concern.
Coastal-dwelling dolphins are exposed to toxic pollutants such as mercury and PCB and as carnivores tend to concentrate more toxins in their bodies.
Such toxins have been correlated with immune system damage and failure in calving.
Cool Facts Bottlenose dolphins in Shark Bay, Australia learned to wear sponges over their beaks while foraging among sharp coral—the only known case of cetacean tool use.
A dolphin's nostrils have shifted to the top of the head, becoming a blowhole that permits easy breathing at the water's surface. A bottlenose dolphin contains three times more blood than a human by body weight, increasing the dolphin's oxygen-storage capacity during dives. When asleep, a dolphin keeps half of its brain awake in order to keep breathing.Common dolphins are not common in captivity.
But on at least three occasions, a beached common dolphin in California was nursed back to health at SeaWorld San Diego, but deemed unfit to release back to the ocean.
These common dolphins remained at SeaWorld with the bottlenose dolphin leslutinsduphoenix.com: Artiodactyla. The Common Bottlenose Dolphin Organism common name and phylum, class, order, family, genus The common name for Tursiops truncatus is the common bottlenose dolphin, phylum Chordata, class Mammalia, order Cetacea, family Delphinidae, of the genus Tursiops, External characteristics As shown in Figure 1 below, the bottlenose dolphin has a streamlined body that provides maximum speed .
Bottlenose dolphins generally do not need to dive very deeply to catch food. Depending on habitat, most bottlenose dolphins regularly dive to depths of m ( ft.). They are, however, capable of diving to some depth.

An Introduction to the Nature of the Bozzlenose. Bottlenose dolphins show a variety of cognitively advanced communication skills, such as vocal production learning, syntax comprehension, and referntial labeling.
The bottlenose dolphin Bottlenose dolphins belong to the delphinid family of the mammalian order cetacea (whales, dolphins, and porpoises).
