Black mussel
Xenostrobus sp.
Family Mytilidae

Unlike its relative, Musculista senhausii, Xenostrobus does not build byssal nests, but prefers to live gregariously on drier habitats attached to rocks, barnacles and oysters away from the muddy bottom.

Under strong light, the shell is dark purple and golden brown, but in the shade, they appear a uniform black.

In spite of their small size, they are able to tolerate long periods out of water.
