A common, secretive species of inshore reefs (Ref. 34024). Lives on rocky shores, often buried in sand, mud or silt below stones or other hard substrate. Specimens in collections often had medium to coarse grained quartz sand trapped in the gill opening (a sand-bottom adaptation and might explain why it is so rarely caught together with D. hoesei, even though both species live in the same general area of south-eastern Australia Depths down to 5 m. A female specimen (AMS I.16469-016, 62 mm SL ) was found to contain two pale unpigmented embryos, 6-7 mm SL. Maximum length for female taken from Ref. 57886.
