Thalassophryne amazonica

A rarely seen and cryptic species found throughout the middle Amazon, the Prehistoric Monster Fish is actually a pure freshwater species of toadfish. Like its marine relatives, it is an ambush predator, lying in wait (often buried in sand) for prey to swim by. It is also venomous, and care should be taken when netting or otherwise handling the fish. In the aquarium, they are shy and spend most of their time hiding and camouflaged to their surroundings but can be weaned onto non-live food over time.
