Mimic octopus showing typical pattern. The mimic octopus was first discovered off the coast of Sulawesi, Indonesia in 1998 on the bottom of a muddy river mouth. [5] [6] It has since been found to inhabit the Indo-Pacific, ranging from the Red Sea and Gulf of Oman in the west to New Caledonia in the east, and Gulf of Thailand and the Philippines in the north to the Great Barrier Reef in south.
Video of Octopus cyanea moving and changing its colour, shape, and texture Octopuses use camouflage when hunting and to avoid predators. To do this, they use specialised skin cells that change the appearance of the skin by adjusting its colour, opacity, or reflectivity.
Like all octopuses, they can change shape easily, which allows them to squeeze into crevices much smaller than themselves. This, along with piling up rocks outside the entrance to its lair, helps safeguard the octopus from predators. Variable ring patterns on mantles of Hapalochlaena lunulata
This increased distinguishable shape of the optic lobe is likely due to the change from planktonic to benthic life as they grow and develop. [12] Where many other currently studied octopus species have only five gyri, the A. capricornicus has seven which suggests that these organisms are more behaviorally complex. [11]
An octopus in the Maldives put on a spectacular show for a diving instructor recently when it modeled its ability to change color to match its environment.Pablo Dutto, a diving instructor living ...
They have eight arms (like any other octopus), but these affixed together in an umbrella shape. [6] However unlike other octopus, they are unable to camouflage by changing skin color and texture. [7] They have a gelatinous body, which spreads into a parachute shape when maneuvering through dimly lit water. [6]
It has the common name algae octopus due to its typical resting camouflage, which resembles a gastropod shell overgrown with algae. It is small in size with a mantle around the size of a small orange ( c. 7 cm or 3 inches) and arms 25 cm (10 inches) in length, and is adept at mimicking its surroundings.
Coleoids can change the shape of this sac, called the cytoelastic sacculus, which then causes changes in the translucency and opacity of the cell. By rapidly changing multiple chromatophores of different colors, cephalopods are able to change the color of their skin at astonishing speeds, an adaptation that is especially notable in an organism ...
