There are no unique autapomorphies.
Occurs in swampy areas with warm, murky water. Found in weedy, mud-bottomed and sand-bottomed canals and drainage ditches (Ref. 5723). Prefers coastal plains and slow moving waters of the lower river valleys (Ref. 7335). Feeds on worms, crustaceans, insects and fish (Ref. 7020).
