Numerous dark spots on the anterior part of its body and head. Lacks plates on ventral surface of the isthmus, wider snout and wider lower jaws. Dark in coloration (Ref. 37032).
Facultative air-breathing (Ref. 126274); Adults occur in sluggish mud or sand-bottomed pools of quiet lowland streams and lakes. Usually found near vegetation.
Life cycle and mating behavior

Observed presence of two distinct waves of developing oocytes in a study indicates a group-synchronous ovary in this species, thus, subsequent spawning during the same breeding season may occur though unverifiable in the same study (Ref. 57432).
