Dolphins are animals that like to eat meat, and fish is one of their main foods. Fish is a very important food for dolphins living in aquariums, zoos and oceans. When they eat fish, they swallow it directly, and they may not chew it at this time. Of course, they can't swallow too big fish, and what they eat is some smaller fish. For dolphins living in the ocean, teeth can play a great role in feeding on fish, but not in feeding. In aquariums, we can often see dolphins eating, and they will swallow the fish directly.
It has been introduced above that no matter the dolphins living in the ocean, or the dolphins living in aquariums and zoos, they all use the direct way of swallowing when they eat fish, and they will not chew. In fact, this is the feeding habits of dolphins, there is no way to change. When dolphins eat fish, they can swallow part of the sea water into their stomach, which can maintain their own osmotic pressure balance, and they also have special body structure to flush out excess salt, which will not cause harm to their body.
After swallowing the fish, these small fish can directly enter the intestinal tract of dolphins, because dolphins are rectal animals, which makes dolphins do not chew when eating, can be swallowed directly. But the size of the fish can not be too large, so the dolphins eat mainly small fish.
