Liloa
sp. #2
 
Liloa sp. #2
Maximum size:  13 mm (extrapolated from shell length).

Identification:  This distinctive species has a transparent, cylindrical shell with a thin straw-colored periostracum. It lacks spiral striae and may sometimes be slightly broader below the midline. Rarely, it may have a few opaque white spots. The animal is approximately twice the length of its shell and cannot withdraw fully. It is translucent-cream frosted with white and decorated with brown spots.

Natural history:  Liloa sp. #2 is a moderately common haminoeid found in mixed habitats from < 1 to 18 m (< 1 to 59 ft). It occurs in protected to moderately exposed locations, usually near the edges of sand patches or in rubble. It is nocturnal, burying itself in sand during the day, and lays a white, spherical egg mass. The eggs hatch in about three days in the laboratory.

Distribution:  Maui and Midway.

Taxonomic notes:  This species is listed in Severns, 20ll as Atys sp. but recent DNA work suggests that it's in the genus Liloa. (Manuel Malaquais, pers. com.) Shells are present in various mixed lots at the Bishop Museum.
