Fish That Slither
Eels have an elongated, snake-like body, making them easily recognizable when compared to other bony fish. Their long dorsal fin is merged with its caudal and anal fins, making one continuous fin along the length of its upper body. While they spend most of their adult lives in freshwater, most species migrate to the ocean to spawn.
They can be found in tropical and temperate waters all around the globe. They are bottom dwellers so when diving with eels, look for them to be hiding in burrows, masses of plants, and between rocky substrate. You can see them in almost every type of freshwater site including rivers, lakes, streams, and even muddy quarries.
