What does it appear like?
Fully grown, this octopus has an arm span of round 60 cm. Its physique is patterned with brown and white stripes and spots.

Where does it reside?
The distribution of the mimic octopus appears to be restricted to the Indo-Malaysian archipelago. It is present in water 2-12 m deep, usually close to the mouths of rivers the place the seabed is silty or sandy.


The camouflage talents of octopuses and their kinfolk, the squids and cuttlefish, are second to none as they're ready to rapidly change their shade to mix in with their background. One species, the mimic octopus, is the undisputed king when it comes to disguise. Not solely can it change its shade as and when it wants to, however it may well additionally use its fl exible physique to undertake the looks and actions of quite a lot of sea creatures. In its regular foraging guise, the octopus inches alongside the seabed looking for appropriate prey, exploring tunnels and burrows with its lengthy, delicate arms. Any crustaceans, worms, or small fish quaking within the burrows will attempt to swim for security, solely to be ensnared by the webbing between the higher elements of the octopus’s arms. Although the mimic octopus is a predator, the naked, silty seabed is a harmful place for a big, soft-bodied animal. Predators abound, and many might simply make quick work of this grasp of disguise. Should the octopus spy hazard, it attracts its arms right into a leafl ike form, adjustments shade to match the seabed, and swims offwith undulations of its physique. The posture, shade, and significantly the motion are startlingly related to numerous fl atfish present in the identical space. These fl atfish have venom glands on the base of their dorsal and anal fins, and many predators give them a large berth. In conditions when the predator isn’t fooled by the previous fl atfish trick, it swims up from the seabed and splays its arms broad. Cruising slowly by way of the water on this posture, it seems to be for all intents and functions like a lionfish brandishing its venomous spines. The approaching predator has handled lionfish earlier than, understanding their stings to be significantly painful, so it swims offand searches for simpler pickings. The mimic octopus continues on its foraging rounds and then by chance swims by way of the breeding floor of a damselfish, which occurs to be fiercely territorial. The fish doesn’t take kindly to this intruder, and it goes on the offensive. With an indignant damselfish bearing down on it, the octopus makes use of yet one more of its impersonations and makes for the closest gap. It adjustments shade and sample and sticks six of its arms into the outlet, leaving two on the floor heading offin totally different instructions, waving sinuously within the water. Hey presto—a convincing impersonation of a banded sea snake, an animal that can fairly fortunately eat a damselfish. The aggressive fish will get the message and backs off. As splendid as these impersonations are, they don't seem to be the octopus’s complete repertoire. Some predators could also be invulnerable to the toxic spines of fl atfish and lionfish and unfazed by the venomous chunk of a sea snake. In these circumstances, the octopus could swim to the floor, absolutely prolong its many arms, and float slowly again towards the seabed in a lot the identical means as sure jellyfish present in the identical waters. Even if the stinging cells of a giant jellyfish should not sufficient to deter some hungry predators, the octopus takes to the seafl oor, and on a mound of silt, it raises its arms above its physique to give a really convincing impression of a giant, stinging anemone.

Key Facts

  • The mimic octopus was solely formally found in 1998, and its superb repertoire of impersonations was solely found in 2001.
  • Although octopuses, squid, and cuttlefish are most likely probably the most adept camoufl age artists within the animal kingdom, mimicry seems to be very uncommon. In most instances, mixing into the background could also be a much more efficient defensive tactic than attempting to appear like one thing else, particularly if the impersonation is a poor one. Many species of octopus reside in areas the place there are quite a few locations to conceal themselves, akin to reefs or the rocky seabed. Should they discover themselves caught quick within the open, they'll change shade within the blink of an eye fixed to match their backdrop. The mimic octopus doesn't have this selection. It lives in a habitat the place cowl is in brief provide, so the flexibility to impersonate numerous harmful neighbors is a really fascinating trait. It is probably going that the octopus picks its disguise, relying on the menace. Very few animals can do that to the identical extent because the mimic octopus.
  • Color altering in octopuses is made potential by specialised pores and skin cells referred to as chromatophotophores. These cells will be stretched and squeezed by muscle mass round their perimeter. When the muscle mass contract, the cell is drawn out into a big, fl at plate. In this state, the pigment within the cell covers a big space. When the muscle mass calm down, the cell contracts, and the pigment spot is way much less apparent to the observer. The pigment in these cells could also be yellow, orange, purple, blue, or black. All of these colours could happen in teams or layers. The visible impact of these shade cells is enhanced by underlying reflective layers referred to as iridocytes, which fluctuate the shade and the tone of the colour directed towards the observer. With this elegant system ,the animal can talk with a riotous show of shimmering colours or mix into the background.
  • The mimic octopus can be the one identified octopus species that traverses tunnels and burrows to conceal itself from predators and to seek for food. When surveying its environment, it might undertake a sentinel posture in an appropriate burrow entrance with solely its eyes and head protruding of the outlet.
  • The octopuses and their kin are, arguably, the head of invertebrate evolution. Their subtle anatomy, complicated conduct, and studying talents distinguish them from the overwhelming majority of different invertebrates. Although they're acquainted to everybody, there may be nice deal nonetheless to find out about these fascinating animals.
