Summary
| Description |
Español: Especies del género son nocturnas y salen de su concha por la noche para alimentarse de la capa de biopelícula que cubre los sustratos rocosos. Son sensibles a la luz solar y a la fuerte acción de las olas, y por eso buscan grietas y la parte inferior de las rocas que son los lugares donde se refugian. Se han registrado la presencia de pulpos como depredadores.
Especies del género, a medida que crecen, reabsorben las partes posteriores de su concha, ampliando la cámara interior desde dentro para acomodar su masa visceral relativamente amplia. Este proceso también permite al caracol mantener una reserva de agua dentro de la concha, una adaptación clave que facilita la refrigeración por evaporación y evita la desecación con la exposición por encima de la línea de marea. Dos especies identificadas son: Nerita tessellata y Nerita versicolor.English: Species of the genus are nocturnal and emerge from their shells at night to feed on the biofilm layer that covers rocky substrates. They are sensitive to sunlight and strong wave action, and therefore seek out crevices and the underside of rocks where they take refuge. The presence of octopuses as predators has been recorded.
Species of the genus, as they grow, reabsorb the posterior portions of their shell, enlarging the interior chamber from within to accommodate their relatively large visceral mass. This process also allows the snail to maintain a reserve of water within the shell, a key adaptation that facilitates evaporative cooling and prevents desiccation with exposure above the tide line. Two species identified are: Nerita tessellata and Nerita versicolor. |
