The octopuses seen in the videos threw silt, shells, and algae at other nearby octopuses. To do so, they gathered up the debris underneath their bodies using their arms.
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.
O. briareus usually mates during the day and only the male octopus can initiate or stop the mating process. After the female octopus has been fertilized, she can store the sperm in her oviduct for at most 100 days. After finding a suitable lair, the female then lays eggs. Some females have been known to seal themselves in their lair while pregnant.
Wild animals can experience injury from a variety of causes such as predation; intraspecific competition; accidents, which can cause fractures, crushing injuries, eye injuries and wing tears; self-amputation; molting, a common source of injury for arthropods; extreme weather conditions, such as storms, extreme heat or cold weather; and natural disasters.
Researchers believe the shorter brooding period near warm hydrothermal springs increases a hatchling octopus’ odds for survival. Mystery of octopus garden in ocean’s midnight zone solved by ...
It is surmised that the octopuses used bivalves for the same purpose before humans made coconut shells widely available on the sea floor. [37] [38] Other sea creatures construct homes in a similar manner; most hermit crabs use the discarded shells of other species for habitation, and some crabs place sea anemones on their carapaces to serve as ...
Some members of an octopus species hunt cooperatively in groups with fish, a new study found — an indication that some octopuses have richer social lives than scientists understood.
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 ...
