authority not recorded
Thalassophryne amazonica is a freshwater toadfish from Amazon tributaries in Ecuador, Peru and Brazil. The only freshwater member of its genus, it spends most of its time buried in sand and is an obligate piscivore that needs a constant supply of live fish. Like other Thalassophryne, it is venomous, with hollow spines on each opercle and the dorsal fin, though its venom is not known to be very potent.
