Imagem de Granulina margaritula (Carpenter 1857)

Descrição:

These tiny snails, about 2 mm, are virtually unknown as few recognize them hidden among grains of sand or on green algae as here. When one of its predators, the six-armed seastar Leptasterias pusilla approaches, the little snails flee while raising their beautiful protective mantle as this one is starting to do. We arranged this encounter in our lab.
