The mimic octopus

The ocean’s eight–armed impression artist

In 1998 a fantastic creature was discovered off the coast of the island of Sulawesi in Indonesia. The Mimic Octopus (Thaumoctopus mimicus) is the first living thing ever observed to imitate the shape, colour, texture, posture and behaviour of several other animal species. It performs multiple impersonations as it crosses the ocean floor.

Quick change artists

All octopus species can change the colour and texture of their skin to camouflage themselves, which is amazing in itself, but nothing like the Mimic Octopus’s behaviour had ever been previously recorded. Mimic Octopuses regularly impersonate (mostly) venomous creatures such as:

Banded Sole—the octopus imitates this flat fish with its poisonous spines by flattening out, trailing its legs behind and travelling in the same undulating manner.

Jellyfish—the octopus rises to the surface and then descends with its arms trailing as it pulses downwards, conspicuously ‘jellyfish-like’.

Sea snake—the Mimic changes its colour to the distinctive black and light stripes of the banded sea snake. It hides its body and six legs in a hole while it aligns its remaining two exposed arms in opposite directions, moving them like the venomous snake.

Lionfish—the octopus boldly swims in the open water, transforming its tentacles to appear like the poisonous barbed fins of a lionfish, and copies its movement.

Although the exact number of things it can mimic is unknown, some scientists believe this creature is able to impersonate up to fifteen separate creatures, including stingrays, sand anemones, crabs and mantis shrimp.

Many cephalopods1 can change their shape and colour to match background patterns and textures,2 even impersonating specific objects (rocks, plants, coral) in their immediate environment. The Reef Squid (Sepioteuthis sepioidea) can even hide in the ‘background’ of a school of parrotfish by impersonating one, but none of that compares to the Mimic Octopus’s ability to impersonate various animals without being among them. They are mimicking other creatures’ visual and behavioural characteristics from ‘memory’.

An octopus may be predator or prey. Camouflage and disguise can obviously be useful in both situations, though the Mimic Octopus’s propensity to imitate venomous creatures is more likely to be of use in deterring those seeking to have it for dinner.

What to wear?

The Mimic Octopus is also able to make seemingly intelligent decisions about which of the multiple ‘personalities’ to choose from. For example, when attacked by damselfish, it mimics the banded sea snake which is known to hunt damselfish. It ‘discerns’ what mimicry behaviour is most appropriate for each situation.

An evolutionary explanation?

Evolutionary researchers discussing the Mimic Octopus’s abilities claim:

The open sand and mud habitat of the Mimic Octopus is a particularly exposed and predator-rich environment, and may explain why mimicry has evolved in this species … Octopuses lack the rapid escape capabilities of squids, and may have been able to occupy this foraging niche only through the evolution of complex mimicry.3

But this only explains why the Mimic’s abilities are useful in such an environment, not the process that developed them. Having four-wheel drive is useful in rough terrain, but that hardly explains the origin of this drive mechanism.

Some researchers have wondered whether sexual selection, a particular type of natural selection, may be involved as well; genes for something preferred by the opposite sex are obviously more readily propagated. One paper says:

Complex behaviours may simply be courtship displays misinterpreted as mimicry. Alternatively, mimicry may have originally evolved as a result of selection for predator deterrence, but may now also be used in mate choice. … [perhaps] females prefer males with large impersonation repertoires.3

But the same paper admits that: “at present there is no evidence to support this possibility”. In fact, the evidence points away from it. Both sexes display mimicry, and it is observed when no other octopuses are around.

In any case, sexual selection is just one special form of natural selection. And as we have often pointed out, selection is a fact, but it can only select from genetic information already in existence. Informed evolutionists know that selection has culling abilities, but not creative ones.

That leaves evolution with only mutations, random genetic accidents, as a source of the information for such mechanisms. So it is no wonder that an evolutionist would have a hard time attempting to explain creatures with mind-boggling behaviours and abilities like the Mimic Octopus in naturalistic terms.

What the animal is doing is fantastic. And it is able to do it all because of the complex, God-designed genetic programming in its DNA.

Please explain …

To fully understand what this creature can do, imagine trying to reverse engineer it to make a machine that can do the same thing. Imagine then only having the blind process of accidents plus selection to explain something even the brightest human engineers cannot do.

And think about this: the Mimic must have an incredibly accurate sensor array constantly feeding data to a monitoring system capable of detecting and reacting to different predators. It must also have a ‘database’ of the different predators so it can know how to react appropriately when it sees each one.

This database somehow needs to take into account things like the offensive and defensive capabilities of each predator, as well as which animal is its natural enemy, so that imitating it has the most likelihood of being a successful deterrent. And then the Mimic must be able to consider unseen predators within any environment, e.g., ‘If I travel in this open area without much cover, I could be attacked by X, Y or Z so I should disguise myself as A, B or C, etc.’

Once all of these decision-making processes have resulted in a particular creature of choice to mimic, it must access another database of information that contains separate, incredibly detailed ‘files’ for all of the different creatures it can mimic (including the other creature’s behaviour, texture, posture, colouration, speed, motion, etc.).

The Mimic now needs to manipulate its own structure, texture, colour and posture. It requires a physical form that can be changed almost instantaneously to expand, contract, become extremely rigid or soft, rough or smooth or multi-textured and even multi-coloured and precisely patterned. And all of these abilities are dependent upon accessing and utilizing copious amounts of genetic information.

All or nothing

One also has to be immensely creative to try to explain how such finely coordinated mechanisms, often seemingly requiring each other to be useful, could have arisen without forethought or pre-planning, both of which are anathema to evolution. As leading atheopathic evolutionist Richard Dawkins said about foresight in evolution:

There’s no room in natural selection for the sort of foresight argument, that says: ‘Well we’ve got to let it persist for the next million years and it’ll start becoming useful’. That doesn’t work. There’s got to be a selection pressure all the way …4

Changing their tune

However, the relentless discovery of new examples of mind-blowing abilities in living things appears to have some evolutionists changing their tune. The same science article postulated that perhaps evolution is ‘intelligent’!

Evolution may be more intelligent than we thought, according to researchers. In a new article, the authors make the case that evolution is able to learn from previous experience, which could provide a better explanation of how evolution by natural selection produces such apparently intelligent designs.

It goes on to say:

… a key feature of intelligence is an ability to anticipate behaviours that will lead to future benefits. Conventionally, evolution, being dependent on random variation, has been considered ‘blind’ or at least ‘myopic’ —unable to exhibit such anticipation. If evolution can learn from experience, and thus improve its own ability to evolve over time, this can demystify the awesomeness of the designs that evolution produces. Natural selection can accumulate knowledge that enables it to evolve smarter. That’s exciting because it explains why biological design appears to be so intelligent.5

Evolution ‘anticipating’, i.e. ‘thinking’, exhibiting foresight? Such comments would likely have Charles Darwin metaphorically turning in his grave! These comments reveal that in the face of observational evidence for intelligent design, a philosophical commitment to naturalism6/atheism seems to prevail, regardless how irrational the attempt.

The Lord has done this

In the end, ‘evolutionary science’ is mostly storytelling for an atheistic worldview. When considering the origin of an amazing animal like the Mimic Octopus, consider Job 12:7–9:

But ask the beasts, and they will teach you; the birds of the heavens, and they will tell you; or the bushes of the earth, and they will teach you; and the fish of the sea will declare to you. Who among all these does not know that the hand of the Lord has done this?
