Indomodulus tectum (Gmelin, 1791)

Indomodulus tectum appears to be the only species in the family Modulidae found in the Marshall Islands. The shells are common on hard lagoon, pinnacle and seaward reefs, usually out in the open but hard to spot due to the typical heavy encrustation of algae and other growths.

The most colorful part of the species is the operculum and foot visible when the animal is retracted back into its shell.
