The Pfeffer's Flamboyant Cuttlefish or Metasepia pfefferi is a robust-looking species, having a very broad, oval mantle. This particular species of cuttlefish is the only one known to walk upon the sea floor. Due to the small size of its cuttlebone, it can float only for a short time. The species is active during the day and has been observed hunting fish and crustaceans.

The Blue ringed octopus or Hapalochlaena lunulata is the most deadly of all cephalopods. The common name comes from the bright blue rings that appear when the blue-ringed octopus is alarmed. feeds on small crabs, hermit crabs, and shrimp that it hunts during the day. Two types of poison secreted by two separate poison glands are used against prey and predators.

The Mimic Octopus or Thaumoctopus mimicus is a species of octopus that has a strong ability to mimic other creatures. It grows up to 60 cm (2 feet) in length. Its normal colouring consists of brown and white stripes or spots. Based on observation, the mimic octopus may decide which animal to impersonate depending on local predators. For example, when the octopus was being attacked by damselfish, it was observed that the octopus appeared as a banded sea snake, a damselfish predator. The octopus impersonates the snake by turning black and yellow, burying six of its arms, and waving its other two arms in opposite directions.
