Range and natural history
It lives mainly in low-elevation fresh water, with some use of mildly brackish river mouths. Habitats range from flowing rivers to still water. It is more abundant near the coast, while records farther upstream tend to involve larger individuals.
This is an ambush predator that waits on the bottom, beneath stones or along overhanging banks, for shrimps and fish. Its behavior makes cover and bank structure meaningful parts of its habitat, beyond whether the water is simply labeled a river or lagoon.
