How do animals survive in the trenches?

How do animals survive in Mariana Trench? A group of deep-sea creatures have lung-like swim bladders which help in controlling their buoyancy. The swim bladders do not collapse because in the deep sea the gas inside is equivalent to the pressure of the water outside.

What can be found in ocean trenches?

The types of rocks found in these ocean trenches are also asymmetrical. The oceanic side is dominated by thick sedimentary rocks, while the continental side generally has a more igneous and metamorphic composition. Some of the most familiar ocean trenches are the result of this type of convergent plate boundary.

Do animals live in the deep ocean?

Answer: There are several ways deep-ocean animals survive in such an environment. First off, the deep ocean is dark because sunlight can’t penetrate very far into the water. Many animals make their own light, called bioluminescence, to communicate, find mates, scare predators, or attract prey.

What fish live in trenches?

Snailfishes
“Snailfishes have adapted to go deeper than other fish and can live in the deep trenches. Here they are free of predators, and the funnel shape of the trench means there’s much more food,” said co-author Thomas Linley of Newcastle University. “There are lots of invertebrate prey and the snailfish are the top predator.

The twilight zone is also known as the disphotic zone. Animals that live in the twilight zone include: lantern fish, rattalk fish, hatchet fish, viperfish, and mid-water jellyfish.
