Barnacles
Although barnacles look like molluscs because of their shell-like covering, they are in fact crustaceans. They are divided into two groups: non-stalked or 'acorn' barnacles, which are surrounded by plates, and stalked or 'goose' barnacles, which are attached to the end of a stalk. The hard, white, cone-like acorn barnacle predominates in Malaysia, attaching itself to rocks and any other hard surface that gets covered by water. Most species in Malaysia grow no more than a few millimetres tall and live in dense colonies primarily in the intertidal zone.
