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 ...
Wunderpus photogenicus, the wunderpus octopus, is a small-bodied species of octopus with distinct white and rusty brown coloration. [2] 'Wunderpus' from German "wunder" meaning 'marvel or wonder'. [3] Due to the appearance and behavior of the wunderpus, it is frequently confused with its close relative, the mimic octopus.
The optic gland in female octopuses is associated with their maternal behavior of guarding their eggs without feeding. [2] This self-starvation results in the death of the female octopus before her eggs have hatched. [3] In captivity, some starving females also self-mutilate and entangle their arms in an apparent effort to die even faster.
The blanket octopus male is an example of sexual-evolutionary dwarfism; females grow 10,000 to 40,000 times larger than the males and the sex ratio between males and females can be distinguished right after hatching of the eggs. [128] Egg cases laid by a female squid
Octopuses are mostly loners, and even their mating is typically done from a distance. One species, however, was seen exhibiting behavior that was not only uncharacteristically social but almost ...
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]
