(^7) Octopus Like the cuttlefish and squid,
an octopus is an intelligent animal with
excellent eyesight. It uses the strong suckers
on its eight long arms to catch crabs.
(^8) Whelk A type of sea snail, the whelk
uses its acute sense of smell to track down
dead animals in the water for food.
(^9) Scallop Like clams, scallops are two-shelled
bivalves. By snapping their shells shut, they
can shoot through the water when they need
to escape danger.
(^10) Mussel All mussels attach themselves to
rocks with strong threads, and live by pumping
food-rich water through their bodies.
(^11) Sea slug Many sea slugs have flamboyant
frills. Bright colours act as a warning to
predators to leave them alone.
(^12) Cuttlefish Unlike most molluscs, a cuttlefish
has an internal shell. This can be filled with
air to make it buoyant, so the cuttlefish can
drift through the water after its prey.
