Size: up to 15cm
most marine mussels the shell is longer than it is wide, being wedge-shaped
or asymmetrical. The external colour of the shell is often dark blue,
blackish, or brown. Mussels feed on microscopic sea creatures. Marine
mussels are usually found clumping together on wave-washed rocks. The
clumping habit helps hold the mussels firm against the force of the waves.
Where to See: Anywhere on the shore, the living Mussel can
also be found underneath the seaweed.
