Comments: Occurs in weedy canals and tolerates poorly oxygenated waters and salinity to 40 ppt.  Occurrence in saline (34-37 ppt.) water in Florida seems to be a case of local acclimatization.  Formerly used in medical research.  Total length 14 cm (Ref. 26938).  Mostly freshwater, sometimes brackish (Ref. 26938).  Piscivore (Ref. 79012).
