Migrators
Here's something that we thought was really weird. At night , off the coast of Bermuda, there is a nocturnal migration of tiny (some of them microscopic) deep-sea creatures to the surface waters so they can eat microscopic plants.
These migrators are so small and have to swim so far, that it would be " like a person walking 25 miles each way to get to and from breakfast".according to Dr. Debbie Steinberg, a marine scientist for the Bermuda Biological Station for Research.
There are different kinds of migrators. Euphausiids, also called "krill", look like tiny, see-through shrimp. They wind up being food for whales.
Copepods are also known as "insects of the sea" . There are more these animals than any other type of animal on earth.
