Threadless Blenny

Oviparous, distinct pairing (Ref. 205).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 6 - 10; Dorsal soft rays (total): 20 - 24; Analspines: 2; Analsoft rays: 16 - 19

Adults occur in estuaries and freshwater habitats, frequently where mangrove are abundant. Presence of toxic buccal glands associated with the grooved canines. This is avoided by predators which even reject it unharmed if they try to ingest it. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Both fang and venom gland is present (Ref. 57406).
