What snails do underwater fish eat?

1, the growth environment of benthic fish

Submerged fish is a kind of deep-sea fish, which mainly lives in the water depth of 500 meters to 2000 meters. It is a marine creature that adapts to the extreme deep-sea environment. Therefore, the food source of marine diving fish also has certain particularity. A good growth environment is very important for the survival and reproduction of benthic fish.

They live in a special water layer, which is rich in all kinds of microorganisms, algae and other organisms. Their inner walls are soft and suitable for swallowing small zooplankton. In addition, benthic fish develop in deep-sea environment, and their food source is relatively simple, with a large number of deep-sea conchs as the main food source, so snails suitable for predation need to grow in their living areas.

2. Snail food of bottom fish

The benthic fish mainly prey on the following deep-sea conchs:

(1) Bottle snail: This is a kind of deep conch, which looks like a bottle and grows at the bottom of the deep sea. Underwater fish can open their mouths and swallow a whole bottle of snails into their mouths.

(2) Octopus: This snail is large, with a spiral body and a threaded surface, and often grows in deep-sea sediments. Underwater fish can cut the octopus with sharp teeth and swallow it.

(3) Octopus: This is a rare deep-sea snail that can grow to a depth of 3,000 meters. Due to the harsh growth environment, its number is less than other deep conchs, but its nutritional value is higher.

3. Feeding patterns of benthic fish.

When benthic fish preys on deep conch, it has a unique way of intake.

They open their mouths to bring the surrounding water into their mouths, then put it back into the water after being filtered by filters such as gill arches, swallow plankton and snails into their mouths, and then the whole water enters the stomach for digestion.

In addition, benthic fish will take passive feeding at night, that is, floating in the water, waiting for the prey to enter the mouth actively.

4. Impact of benthic fish on ecological environment.

As an important part of the deep-sea food chain, benthic fish play an indispensable role in the balance of marine ecosystem.

They can control the number of deep-sea conch, keep the balance of deep-sea creatures and promote the reproduction and growth of deep-sea plankton.

At the same time, the study of benthic fish is also of great significance, which can help us better understand the deep-sea ecological environment, improve the level of marine protection and develop deep-sea resources.
