However, this behavior lacks the complexity of the octopus's fortress behavior, which involves picking up and carrying a tool for later use. (This argument remains contested by a number of biologists, who claim that the shells actually provide protection from bottom-dwelling predators in transport. [39]) Octopuses have also been known to ...
The more scientists study octopuses, the more we learn how fascinating these creatures really are. Octopuses are incredibly intelligent, displaying all kinds of amazing behavior like completing ...
The common octopus can hear sounds between 400 Hz and 1000 Hz, and hears best at 600 Hz. [61] Octopuses have an excellent somatosensory system. Their suction cups are equipped with chemoreceptors so they can taste what they touch. Octopus arms move easily because the sensors recognise octopus skin and prevent self-attachment. [62]
For example, when the octopus Callistoctopus macropus is threatened, it will turn a bright red brown color speckled with white dots as a high contrast display to startle predators. Conspecifically, color change is used for both mating displays and social communication.
The common octopus (Octopus vulgaris) is a mollusk belonging to the class Cephalopoda. Octopus vulgaris is one of the most studied of all octopus species, and also one of the most intelligent. It ranges from the eastern Atlantic, extends from the Mediterranean Sea and the southern coast of England , to the southern coast of South Africa.
The pattern can serve as a unique identifier as it varies among individuals. [2] Though LPSO has similar body color patterns to other octopuses like Octopus chierchiae, [9] Octopus zonatus, [10] Abdopus spp., [11] Thaumoctopus mimicus, [12] and Wunderpus photogenicus, [12] the body patterns it exhibits are unique to the species.
The largest known octopus garden in the world has been discovered off the central California coast.. A new study published in Science Advances reveals the existance of a hot springs close to ...
Deimatic display: Callistoctopus macropus generates a bright brownish red colour with white oval spots when disturbed. Deimatic behaviour is found in cephalopods including the common cuttlefish Sepia officinalis, squid such as the Caribbean reef squid (Sepioteuthis sepioidea) and bigfin reef squid (Sepioteuthis lessoniana), octopuses [15] including the common octopus Octopus vulgaris and the ...
