Who is it?

Genus Anguilla

Eels are serpentine fishes with a cylindrical body. They have small scales embedded in their dermis. Their skin is covered by abundant mucus.

In 2019, 19 species of eels have been identified. Genus Anguilla belongs to the Anguilliformes, which is composed of this single genus sub-group. These species live in tempered as well as tropical oceans.

All eels share a similar reproduction cycle. First, larvae are born in the sea and migrate to the continental shelf where they go through morphological changes. Then, they colonize all the freshwater streams. Using this strategy avoids an intra-species competition.
