HOW
STURGEON EAT
Sturgeon have mouths that seem very peculiar to us. But they
are perfect for eating the way a sturgeon does.
First of all a sturgeon doesn't have any teeth, so even though
they look a little bit like sharks, they can't bite anybody.
Instead they have lips that move in and out. When their lips
are in they look pretty ordinary. But when a sturgeon wants
to eat, its lips expand so that its mouth is like a little
vacuum cleaner. Then it just sucks up its food from the bottom
of the river. This kind of mouth is called protrusible because
it can protrude or stick out from the fish.
CAT INSIDE
STURGEON ?
Sturgeon eat almost
any kind of dead or living animal that it finds on the river
bottom. Some of the things that have been found in sturgeons'
stomachs are fish eggs, small crayfish, shrimp and clams,
bugs and fly larvae, and other fish especially eulachon. Big
sturgeon can eat bigger fish like herring, salmon and flounder
as well as things like crabs, mussels and barnacles. Someone
once even found a dead cat inside a sturgeon. They were pretty
sure the cat was already dead when the sturgeon ate it.
