Catomerus is a monotypic genus of intertidal/shallow water acorn barnacle that is found in warm temperate waters of Australia. The genus and species is very easily identified by whorls of small plates surrounding the base of the primary shell wall; no other shoreline barnacle species in the Southern Hemisphere has that feature. This species is considered to be a relic, as these plates are found only in primitive living lineages of acorn barnacles or in older fossil species. The fact that this is an intertidal species is unusual, because living primitive relic species are often found in more isolated habitats such as deep ocean basins and abyssal hydrothermal vents.

Is it venomous or poisonous?
We have no record of Surf barnacle being toxic, poisonous or venomous. That is not proof that it is safe. Never eat, touch or handle a wild plant, mushroom or animal on the strength of an identification; ask someone qualified.
