Mimic Octopus

Fascinating facts about the Mimic Octopus

• The mimic octopus can switch among a remarkable array of disguises, with researchers counting up to eighteen different marine animals it can imitate. It achieves this by altering not only its colour but also the shape of its body and the way it moves, such as spreading its arms like a lionfish or flattening them like a flatfish.
• A 2008 study recorded a single mimic octopus performing nearly five hundred flatfish impersonations over just five days, indicating that flatfish mimicry may be its favourite disguise. During these bouts the animal holds all eight arms behind its body and propels itself with a jet from its siphon, closely resembling the swimming style of a zebra sole.
• When a group of damselfish began to harass it, the mimic octopus transformed into a banded sea snake, a known predator of those fish, demonstrating an immediate behavioural response to threat. By tucking six arms and extending the remaining two parallel, it recreated the snake's distinctive shape and slithered away using its siphon.
• The mimic octopus grows to about 60 cm in total length, yet its body is no wider than a pencil. It was first found on the muddy bottom of a river mouth in Sulawesi, highlighting its affinity for soft substrates. Unlike most octopuses that hide among reefs, this species seeks shelter in river mouths and estuaries, where it can blend with sand and silt. Its slender build and habitat choice give it a distinct niche among its relatives.
• Mimic octopuses are most often seen on sand or silt at depths shallower than 15 m, a setting that contrasts with the reef habitats favoured by many octopus species. These shallow, murky waters are typical of river mouths and estuaries across their Indo-Pacific range, from the Red Sea to the Great Barrier Reef. Living in such environments means the octopus must rely heavily on its rapid jet-propelled gliding and skin camouflage to hunt and avoid predators.
