The American Eel has a long body that looks an awful lot like a snake’s body. But don’t mistake it for a reptile! The American Eel is actually a fish — a fish that looks like it needs a bit of dental work. Its lower jaw is quite a bit longer than its upper jaw which makes it look like it’s got a bad underbite. It may not be a looker, but the American Eel has bigger fish to fry than these days. This fish has a huge migration. It spawns (releases its eggs) in the Sargasso Sea near the Bahamas, and tiny juvenile (young) eels drift across the ocean then swim back up the St. Lawrence and Ottawa River. But its numbers are dropping fast. The American Eel used to be the most common fish you’d find in the Ottawa River! But now it’s become really rare because dams are blocking it from migrating.
