The living habits of oriental bottlenose dolphins

Scope of activities: 15~85 square kilometers.

Oriental bottlenose dolphins behave in a similar way to other bottlenose dolphins. Most of the time, they prey, give birth or avoid attacks from other predators in groups of 5~ 15. They play with each other, chase and splash water, and some behaviors are related to learning. Its community has a social hierarchy, and the largest dolphins usually dominate.

They mainly feed on bony fish and rely less on cephalopods. Although they can eat all kinds of fish, the main diet is only a few in different areas. In the case of artificial feeding, you can eat 6~7 kilograms of food every day. Their cooperative hunting and foraging actions are characterized by frequent low jumps per minute. They mainly hunt and eat in the morning and afternoon. In shallow waters, there are several methods of predation, including "kicking" fish into the sand with their tails and catching small fish with the coast.

Because the capillaries of the eastern bottlenose dolphins can exchange air faster, their red blood cells are twice as large as those of land animals, and their myoglobin is 2~9 times as large, so they can switch freely between stopping breathing in deep-sea diving and normal breathing in surface swimming.
