CommentVenomous! One of the most dangerous snakes with a highly potent toxin (LD50 = 0,01 mg/kg in mice; FLINDT 2002).

Diversity: Australian “E. schistosa” has been elevated to species status and provisionally referred to Enhydrina zweifeli by Ukuwela et al. 2013.

Synonymy mostly after STEJNEGER 1907 who listed Enhydrina valakadyn as valid species.

Distribution: Probably not in Madagascar fide F. Glaw (pers. comm.). For a map see Sindaco et al. 2013.

Abundance: H. schistosus was the most commonly sighted sea snake during a 1970s survey around the Melaysian Peninsula (Lim & Sawai 1975).

Type species: Enhydrina valakadyen Gray, 1849 is the type species of the genus Enhydrina GRAY 1849.

Habitat: marine and freshwater (Rasmussen et al. 2001). 
EtymologyPresumably named after the Greek schistos (split), in relation to the grey-green coloration of the rock of that name (schist colored) plus the suffix -osus (abundance). The description emphasises the schist-like coloration. (G. Shea, pers. comm., 9 Feb 2024)
