The East Asian common octopus is adapted to a benthic life at the bottom of the sea. Octopus sinensis has long arms with many suckers used for catching prey, a mantle without a rigid skeleton, which allows them to inhabit and hunt in small spaces and crevices in the seabed, horizontal pupils, and versatile skin with ability to change colors and camouflage themselves with the sea floor.
Someday, the researchers say they hope their method can be used to design military vehicles that can automatically camouflage themselves. And other research in recent years has focused on ...
An octopus (pl.: octopuses or octopodes [a]) is a soft-bodied, eight-limbed mollusc of the order Octopoda (/ ɒ k ˈ t ɒ p ə d ə /, ok-TOP-ə-də [3]).The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids.
Octopuses have many different adaptations in order to protect themselves from predators, and many octopuses utilize similar strategies. Some employ camouflage through which they use chromatophores to change their color. Many octopuses use a projection of ink in order to startle and distract predators.
The camouflage it uses to blend with its surroundings is remarkable, making each sighting feel like a small triumph. ... they often attach themselves to the reef wall, blending in by mimicking its ...
Surviving in the wild is no easy feat, but thanks to evolution, many animals evade their predators with a clever deception of the eyes. Since the beginning of time animals have either adapted or ...
In ancient Greece, Aristotle (384–322 BC) commented on the colour-changing abilities, both for camouflage and for signalling, of cephalopods including the octopus, in his Historia animalium: [1] The octopus ... seeks its prey by so changing its colour as to render it like the colour of the stones adjacent to it; it does so also when alarmed .
So, when an octopus encounters a predator, it has the sensory apparatus to detect the threat, and it has to decide whether to flee, camouflage itself, or confuse predator or prey with a cloud of ink.
