Cellana is a genus of sea snails or limpets, marine gastropod molluscs in the family Patellidae, the true limpets. [1]

Distribution

This genus occurs in the temperate and tropical Indo-Pacific oceans, Hawaii (where it is known as opihi) and around Australia and New Zealand. It is also found around Japan, the Red Sea, Mauritius, Madagascar, and South Africa and sub-Antartarctic Islands. One species, Cellana radiata, is cosmopolitan.

They feed by grazing on green macroalgae on the rocky substrates in intertidal zones. They can live up to seven years, most don't get older than 2-3 years. They reproduce by broadcasting their spawn in large, yolky eggs in great numbers (between 20,000 for C. flava and C. denticulata to 230,000 for C. ornata)
