Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Inhabits ponds, swamps, lakes; and vegetated pools, usually with mud or sand bottoms, of small to medium rivers. Also occurs in warm, clear and quiet waters rich in vegetation and snags. Has a preference for mollusks as food thus has potential for the control of snail vectors of schistosomiasis (Ref. 1739, 10294). Oviparous (Ref. 205).
Breed in shallow ponds, lakes or creeks (Ref. 205). Distinct pairing (Ref. 205). Oviparous (Ref. 205).
