Bottlenose Dolphin

Tursiops truncatus

Classifacation

-Domain Eukarya: They are part of the domain Eukarya and this means that their cells have a nucleus.

-Kingdom Animlia: They are all multicellular,they reproduce sexually, and they lack a cell wall.

-Phylum Chordata: These animals have a hollow nerve cord and a complete digestive system.

-Subphylum Vertebrata: They control there movements by moving their muscles and they have a digestive system including a liver and pancreas.

-Class Mammalia: They all have hair at some point in there lives many have it their whole lives and even dolphins have hair at some point in their lives.

-Order Cetacea: They have no claws,they mostly have a hairless body and they have a blowhole on the top of their head.

-Family Delphinidae: The males are normally bigger than the females, these animals have a high social level and they can live in groups of more than 100,000 individuals.

-Genus Tursiops: This genus only includes the Bottlenose Dolphin.

-Species: Tursiops truncatus

General Description

-Length: They can get to the length of just over 13 feet and that would be 4 meters

-Weight: The bottlenosed dolphin weighs about 660 pounds and that is about 300 kilograms

-Color: They are usually black and light grey and there bellies are white and sometimes pink.

-Natural range: Bottlenose dolphins are found in the tropical and warm tempatures

-Diet: Many bottlenose dolphins feed individually and their teeth are used to get their food not to chew they normally swallow their prey whole not by chewing it.

Bottlenose dolphins that are inshore feed on fish and invertebrates near the shore line.

Dolphins that live in the deep water feed on squid and pelagic fish.

-Habitat Description:The bottlenosed dolphin can be found anywhere but polar waters

the bottlenose dolphins that live in the deep water have to come up to the surface breath every 1 to 2 minutes. They can be found in bays, open shorelines, and many more places

The tempature where they live is around 60 and they mostly live in oceans, seas, or other bodies of salt water.

-Predators: Their most common predator would be larger sharks these sharks could include bull sharks, tiger sharks, and also dusky sharks are their most common prey

Physical Adaptations

Bottlenose Dolphins sleep through out the day.When researchers studied bottlenose dolphins sleeping they found that the dolphins sleep for 33% of the day. They also have a constant body temperature and there body temperature is normally 36-37 degrees Celsius or 96.8-98.6 degrees Fahrenheit. This temperature is about the same body temperature that a human would have. The bottlenose dolphin can dive but it does not normally have to dive. They can normally dive 3-46 m or 10-150 ft in depth. They can dive farther if they need to for experimental conditions. Another adaptation would be there breathing. They breathe through one blowhole on the top part of their head.They have a flap that is made of muscle. The flap helps the dolphin hold its breath when they are under water and this helps them survive. Lastly the Bottlenose dolphin can swim. They can swim at low speeds and high speeds. This helps the Bottlenose dolphin survive because it lets them get away from there prey if they are in a dangerous situation.

Behavioral Adaptations

The Bottlenose dolphin has to interact with other species in their life time. Bottlenose dolphins have been seen with many other species. These species could include Toothed whales, pilot whales, Risso's dolphins, spotted dolphins and rough-toothed dolphins. They have also been seen riding waves with grey whales, humpback whales and right whales. This helps them survive because if they are with or friends with one of there predators or something similar this would keep predators away. They also protect and care for animals and also give it. They can go out and investigate and look for different things and come and tell the group about it. They also can help other dolphins when they are hurt or need any type of help such as bringing them to the surface to breathe.This helps them survive because they have other dolphins that can help them in many situations and conditions. They also have Individual behavior. They often ride on waves and jump. They have been seen jumping to the heights of 4.9 m or 16 ft from the surface. When they jump they land on their backs or their sides.They can also carry objects around for catching food.This helps them survive because they can learn how to live alone and they also can jump for safety if there is a dangerous situation. Another adaptation would be that they have activity cycles. They are active in both the day and night. Research has shown that their activities would include feeding, socializing, traveling, and resting. This helps them survive because they can stay active and they can also mate with other dolphins and this generally helps them live and be in there habitat. The last adaptation is that they live in social groups. The groups are built by the age,reproduction stage,and also family relations. This helps them survive because by being in groups they can get there food more easily and they can all help each other through many situations.
