Barnacles of the superfamily coronuloidea are obligate epibionts of various marine mammals, marine reptiles and crustaceans, attaching to the host‘s surface or embedded in their skin. Currently, this superfamily is divided into three families, chelonibiidae, platylepadidae and coronulidae (newman, 1996).
The size distributions (dosima, 1-22 mm; lepas, 1-16 mm) provided no indications of generational discontinuities.
This chapter discusses the barnacles (subclass cirripedia) that make up 1000 marine species. Barnacles are unique among crustaceans in being permanently.
The cirripedia are crustaceans that as adults are usually sessile, at tached to hard substrata or to other organisms. The carapace (man tle) completely envelops the body, and in most forms it secretes a calcareous shell—a trait that led some earlier zoologists to place barnacles in the phylum mollusca.

The purpose of this paper is to document recent additions to the south african barnacle (cirripedia) fauna. New species records were obtained by examining accumulated collections of unidentified material in the iziko south african museum, as well as via material collected directly by the authors. Fourteen species, none of which are new to science, are added to the known fauna, raising the total number of barnacle species recorded from south africa by over 20%, from 69 to 83 species.

They differ from acorn barnacles in that the plates do not form a separate wall and operculum and in having the wall and the cirri it contains elevated above the substratum by a peduncle. The peduncle contains the ovaries and some musculature; it may or may not be armoured by calcareous plates, as in pollicipes and lepas, respectively. Goose barnacles are probably the most commonly observed pedunculate cirripedes.
The barnacle is a hardy animal that is found in or very closely to sea water. Although it is frequently confused for a mollusc because of its hard outer shell, it is actually a crustacean, closely related to crabs and lobsters.

A barnacle is a type of arthropod constituting the infraclass cirripedia in the subphylum crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile and most are suspension feeders, but those in superorder rhizocephala are parasitic.

Sessile barnacles are those that attach themselves permanently to a substrate and live their whole life within their shell. They feed by reaching into the water stream with their legs to catch passing food particles.
