Common bottlenose dolphin and Pacific white-sided dolphin are mammals, alligator snapping turtle are reptiles, and Sand tiger shark are fish.

Common bottlenose dolphins weigh approximately 260 kg.

It is said that they cannot distinguish colors.

In the sea, they eat mainly fish, squid & octopus.
At Noboribetsu Marine Park Nixe, we feed them mackerel, okhotsk atka mackerel, horse mackerel, & sand lance.

They stay still in the cold deep sea to conserve energy as much as possible.
