''Megatrema anglicum'' is a species of acorn barnacle that grows in association with or semi-parasitically on corals and octocorals. It is found in the intertidal zone on the coasts of northwestern Europe and in the Mediterranean Sea. ==Description== ''Megatrema anglicum'' has a pink conical shell on a cup-shaped base and can grow to a diameter of up to . There are longitudinal striations on the shell and the operculum, the lid to the opening through which the barnacle's feeding parts protrude, is depressed, so that the structure is vase-shaped. Another barnacle, ''Verruca stroemia'', is sometimes found at the foot of the coral's calcified cup, but ''M. anglicum'' seems to be the only barnacle species adapted to live in close proximity to the coral's tentacles.
