This bivalve bores deep into coral rock by means of acid secretions. It protects itself by means of a horny shell layer (periostracum). It is especially common in dead coral blocks. It is a filter feeder. (Length up to 8cm).
This shrimp mechanically bores its way into the rock using its powerful pincers, creating a network of tunnels. It filters small organisms which are drawn into their tunnels by the rapid beating of their swimmerets. (Length up to 4cm).
