|Kingdom Animale | Phylum Mollusca | Class Bivalvia|
These pretty shells are found under rocks on reef flats. They are free-swimming, moving by clapping the two shell valves rapidly and forcing water out. The red colouration is due to the pigment haemoglobin. When disturbed, their sticky (but harmless) tentacles attach onto the predators and break off. They are filter feeders. (Shell 2-3cm).
