Max length : 58.0 cm TL mâle / non sexé; (Ref. 86798); common length : 13.5 cm TL mâle / non sexé; (Ref. 12193); poids max. publié: 2.7 kg (Ref. 120584); âge max. reporté: 16 années (Ref. 72462)
Adults occur in fresh, brackish and coastal waters (Ref. 7251). They inhabit pools and other quiet-water areas of medium to large rivers, usually over mud (Ref. 86798). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406).
Assuming same mode of reproduction as in M. saxatilis.
