The blind eel is often called the
nast yi est fish in the ocean. They
are called blind because their small
eyes don’t see in the complete
darkness on the bottom of the
ocean.
Blind eels have ci rcular mouths that they use
to suck on their dead and living fish. They
have teeth on their tongues that allow them
to cut through their prey and eat them.
They are also sometimes called slime eels
because their skin makes a sticky slime. It
makes up to a gallon at a time. It is used to
suffocate predators by clogging their gills
when they try to eat the eel. They belong to
the family called cy clōstōmes which means
they have no scales, no fins, no jaws, and a
mouth shaped like a c i rcle.
These strange fish live 5,600 feet
down at the bottom of the ocean.
