Short description
Identification keys | Morphology | Morphometrics
Distinguished from other species of the genus by its color pattern consisting of large roundish black blotches scattered over a light brown or yellowish ground pigmentation and presence of inconspicuous brown small spots distributed among the large dark spots. Differs further from Synbranchus marmoratus by a higher number of vertebrae and from S. madeira by a shorter post-anal length (Ref. 56782).
Facultative air-breathing (Ref. 126274); The male guards and builds nest or burrow (Ref. 205).
