growth. Dolphins are brought into the world after a long pregnancy and like humans, live with their family for some time but eventually leave in search of a mate with whom they can breed. Dolphins can mate from about 6-8 years of age; this age is where they become an adult.
Additionally, what is the habitat of a dolphin? Dolphins are found living in bodies of water around the world. They inhabit all of the oceans and some important rivers. Most of them live in saltwater, but a few species thrive in freshwater. The habitat of dolphins varies according to environmental factors and food accessibility.
In this regard, what is the food chain of a dolphin?
Bottlenose Dolphin Food Chain Bottlenose dolphins eat larger fish, such as tuna and mackerel. They also eat crustaceans and, if living in open oceans, squid. Tuna and mackerel eat smaller fish, such as coastal flying fish in the Pacific Ocean.
Is a dolphin a fish?

Spradlin, a Federal dolphin expert. ”But people see marine mammals differently, particularly dolphins.
How big is a dolphin brain?
Bottlenose dolphins have bigger brains than humans (1600 grams versus 1300 grams), and they have a brain-to-body-weight ratio greater than great apes do (but lower than humans). “They are the second most encephalized beings on the planet,” says Marino.
Do sharks eat dolphins?
