Freshwater cobbler

The freshwater cobbler, Tandanus bostocki, is a species of catfish (order Siluriformes) of the family Plotosidae. The freshwater cobbler originates from coastal drainages of southwestern Australia, from the Frankland River to the Moore River. This species may reach about 50.0 centimetres (19.7 in) TL.

This species lives in slow-flowing streams, ponds and reservoirs. It also occurs in isolated pools in riverbeds and some freshwater lakes, swimming close to rocky, gravelly, or sandy bottoms. Underwater cavities in river banks and root mounds of sedge tussocks may be utilized for shelter. This species is tolerant of brackish conditions and is venomous.
