This species is easily recognized by its thin, strongly inflated shell marked with broad flesh-colored bands outlined in black. The animal is translucent cream. Hydatina amplustre is a moderately common species in mixed habitats at protected to moderately exposed sites. 

The animals are nocturnal, burying themselves in sand during the day (often under cobbles). It is found from the low intertidal to depths of 1-2 m (3-6 ft). It feeds on polychaete worms (Kay, 1979) and lays a convoluted, cream egg mass attached by a mucous thread. The eggs hatch in about eight days in the laboratory (Daniel Jennings-Kam, pers. com.). Widely distributed in the Indo-Pacific.
