Peronella lesueuri - a beautiful sand dollar of importance in coastal ecosystem processes
The striking Peronella lesueuri (Clypeasteroida - Laganidae), is a large sand dollar up to 15 cm in diameter, with a wide Indo-Pacific distribution. The most noticeable and amazing feature of this species is its bright pink when alive, hence its common name of Pink sand dollar.
It is a shallow burrower and occurs at densities which may influence surface sediment chemistry and community dynamics. Therefore, knowledge of seasonal and diet movement rates and rhythms of this species are a key of interest in understanding coastal sediments biogeochemical dynamics.
