East Pacific red octopus, rescued from a gull near Los Osos, California. Octopus rubescens (commonly the East Pacific red octopus which is a Cephalopod, and also known as the ruby octopus, a preferred common name due to the abundance of octopus species colloquially known as red octopus [1]) is the most commonly occurring shallow-water octopus on much of the North American West Coast and a ...
Using octopus genomics was “an innovative and exciting way” to address an important question about historical climate change, said Douglas Crawford, a professor of marine biology and ecology ...
Vulcanoctopus hydrothermalis, also known as the vent octopus, is a small benthic octopus endemic to hydrothermal vents. [1] It is the only known species of the genus Vulcanoctopus . This vent octopus is endemic to the hydrothermal vent habitat that is located in the East Pacific Rise.
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.
Shifts in available prey may force a change in octopus diets to other, nonshelled organisms. [citation needed] Because octopuses have hemocyanin as copper-based blood, a small change in pH can reduce oxygen-carrying capacity. A pH change from 8.0 to 7.7 or 7.5 will have life-or-death effects on cephalopods. [23]
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.
To combat the intense pressure of the abyssal zone, this octopus species lost its ink sac during evolution. They also use their strand-like structured suction cups to help detect predators, food, and other aspects of their environment. Cusk eel (genus Bassozetus): there are no known fish that live at depths greater than the cusk eel. The depth ...
Climatic adaptations limits to adaptations that have been established, characterizing species that live within the specific climate. It is different from climate change adaptations which refers to the ability to adapt to gradual changes of a climate. Once a climate has changed, the climate change adaptation that led to the survival of the ...
