Beluga is a kind of whale, is a very cute whale. The main food of beluga whales is fish, mollusks and some plankton. Among them, fish is their main food, whether it is living in the ocean belugas, or artificial breeding, living in the aquarium belugas, like to eat fish.
When belugas eat fish, they usually swallow it directly and do not need to chew it. Belugas, which live in the ocean, suck water into their mouths when they swallow. However, they will not swallow all of these seawater, they will use filter plates to filter out most of the seawater, and then swallow the fish and shrimp they catch. Belugas living in aquariums eat fish differently, but it can be said that they mainly use swallowing methods. However, after some artificial training, belugas will also use their teeth when eating fish, chewing them before swallowing.
As mentioned above, belugas usually swallow fish directly instead of chewing it with their teeth first. This is because the feeding habits of beluga whales, they have been accustomed to this way of feeding, can not be changed in the short term, if you want to change, you need long-term training. In addition, when they swallow fish, they can also swallow part of the water into their stomach, which can maintain the physiological balance of their body. Although they swallow the fish directly, there is no need to worry about the harm of fish bones to them, they can secrete special digestive calcium enzymes, which can digest fish bones.
