BIOMIMICRY TAXONOMY
Summary
"When their speed alone is not enough for safety, [cuttlefish] squirt a cloud of dense, dark coloured ink that is synthesised in their bodies. This ink surprises their predators for a few seconds, which is usually enough for them to escape." (Yahya 2002:104)

"Sometimes the ink cloud itself resembles the blobby shape of an octopus and acts as a decoy, allowing the octopus to escape while the predator eyes the blob." (Crump 2005:109)
