Report writing


Elly Broughton


The scientific name for bottlenose dolphins are “tursiops”.
HABITAT:


Bottlenose dolphin are only really found in more temperate and tropical waters. They are normally found around 20 miles offshore in harbor’s bays and lagoons. I myself have only ever seen bottlenose dolphin in warmer waters for example in between Hohaura and Rangiputa. I have also seen a few pods of these dolphins in Fiji.






PREDATORS:


The main predators to Bottlenose dolphins are different types of sharks and orcas. The main types of sharks are tiger, dusky and bull sharks. Orcas are also really high on their predator list and you wouldn’t really think so as orcas are just larger dolphins.


they are very fast animals but can still be overtaken easily and captured by their threats.



DIET-PREY:


These dolphins never chew their food with there teeth. They have big throats and it allows them to swallow their kai in one piece. They really like crustaceans, shrimp and squid. Occasionally they munch on king fish and smaller fish. Adult bottlenoses usually eat between fifteen and thirty pounds a day. These dolphins are really fast and strong swimmers and can easily catch their prey but their predators can also still catch them.





BREEDING:


Female dolphins are pregnant for up to twelve months.


They only give birth to a single calf once every three years. These calves are not born head first but tail first to ensure the calf does not drown. The female normally becomes pregnant when she is six to thirteen years old and will give birth in spring and summer. Dolphins can live up to the age of forty which gives them plenty of time to reproduce.

There is a large amount of dolphins left, approximately six hundred thousand. They are very safe and are nowhere near extinction or becoming endangered.


You will see these dolphin for a long time and will not have to worry about them.
