DiagnosisDiagnosis (genus): Dorsal scale rows 21 at mid body; internasal separates prefrontal and nasals scales; frontal’s contact with the internasal makes this species readily distinguishable from all other homalopsids, including Cantoria violacea which has 19 scale rows at mid body and the prefrontal scales in broad contact. A number of species of Enhydris have 21 scale rows at mid body, but all of them have the nasal scales in contact. D. annulatus also has keeled scales in the first three dorsal scale rows just anterior to the vent. A male is 578 mm in total length with a 108 mm tail; four females were 277–548 mm in total length. See Murphy (2007) for a more exhaustive description.
CommentHabitat: marine (sea snake).

Diet: crustaceans
