DistributionSE China
Indonesia (Bangka, Belitung, Java, Kalimantan, Sulawesi ?, Sumatra, We);
Bangladesh; Cambodia; C/E India (Telangana, Nagaland etc.); Laos;
Malaysia (Malaya and East Malaysia, Borneo, Pulau Tioman [HR 31: 114]);
Myanmar (Burma); Nepal; Bhutan, Pakistan;
Singapore (?); Sri Lanka; Pulau Bangka,
Thailand; Vietnam

Type locality: “Indiae orientalis”  
Reproductionovovivparous 
TypesHolotype: iconotype, based on illustration of Mutta Pam in Russell (1796), Indian Serpents, p. 35, pl. 30 
DiagnosisDiagnosis (genus): Dorsal scales in 21 rows at mid-body, reduced to 17 or 19 posteriorly, prefrontal and internasal usually contacting loreal, second pair of chin shields larger than gulars. Myrrophis may be most easily confused with these snakes. Myrrophis chinensis has 23 rows of dorsal scales, and M. bennettii has 21 dorsal scale rows, reduced to 17 or 15 rows at posterior body, but second pair of chin shields about the same size as the gulars. The hemipenis extends to the seventh or eighth subcaudal in Enhydris and to the tenth subcaudal in both species of Myrrophis (Murphy & Voris 2014: 15)

CommentDistribution: Not in Pakistan fide KHAN 2002 (pers. comm.). Not listed for Sri Lanka by JANZEN et al. 2007. The latest record of this species from Sulawesi is from MEYER 1887. DE LANG & VOGEL (2005) thus consider this species as doubtful for this island. Possibly in Bhutan (Lenz 2012).

Habitat: freshwater

Diet: mostly fish

Type species: Hydrus enhydris SCHNEIDER 1799 is the type species of the genus Enhydris LATREILLE in SONNINI & LATREILLE 1801. 
EtymologyBot genus and species were named after the Greek “enhydris”, meaning water snake.
