They are often found in large numbers in lagoons,

from the intertidal zone to approx. 20 m on sand, rubble or hard reef substrates,

as well as between Halimeda algae.

The shells are often whitish, some are very heavily pigmented.

This winged snail feeds on algae growth and detritus.

Harpago chiragra is often referred to colloquially as the Chiragra spider snail - boat hook.

It lives on sandy bottoms between the lagoons and the reef.

Diet: algae.

It cannot be easily turned over by potential predators,

as the widened mouth of the snail enables a stable position.

It is always visible on top of the sand.

The shell alone reaches a length of approx. 17 cm.
