The banded sculpin (Cottus carolinae) is a mottled brown freshwater fish with dark vertical bands native to swift moving streams of the eastern United States where they dine on insects, various larvae, and occasionally, though sparingly, on other smaller fish or crustaceans.
If there is any fish that lives up to its name it’s the Goliath Tigerfish—a truly gigantic African predator with razor sharp teeth. The largest on record weighed over 150 pounds at nearly five feet in length. For perspective, that’s two German Shepard’s stacked on top of each other, or a welterweight fighter—and a fighter they certainly are.
Piranhas need no introduction being that their teeth and diet have earned them quite the reputation, especially around Hollywood as a super villains aquarium species of choice or as the center of several B-movies.
Gracefully snaking through the water as if under the control of a rhythmic gymnast, the Ribbon Eel is quite the spectacle.
A fish you probably never heard of has one of the most clever camouflage tricks out there, accounts for 65% of the deep seas biomass, and can disrupt sonar.
