Learn more about the feats and features of these cephalopods below! Because octopuses have hemocyanin as copper-based blood, a small change in pH can reduce oxygen-carrying capacity.  Over thousands of years, humans have caught them using lures, spears, pot traps, nets, and bare hands. The giant Pacific octopus is a very intelligent animal that can learn to open jars, play with toys and interact with — and even recognize — its handlers.  To avoid these dead zones, octopuses must move to shallower waters which may be warmer in temperature and less oxygen-rich, trapping the organism between two low-oxygen zones. Common name: Giant Pacific Octopus. Find your thing. Characteristics. He is now looking into whether individuals can alter their protein synthesis in response to changing temperatures, or if it is done over long-term adaptations.

Using tag and recapture methods, scientists found they move from den to den in response to decreased food availability, change in water quality, increase in predation, or increased density (or decreased available habitat/den space) Because their blue blood is copper-based (hemocyanin) and not an efficient oxygen carrier, octopuses favor and move toward cooler oxygen-rich water. This octopus species is very rarely encountered and the few information scientists have managed to gather […] Pacific Octopus with angular geometric lines art design.  The prey base that octopuses prefer (crab, clams, scallops, mussels, etc.) It can be found from the intertidal zone down to 2,000 m (6,600 ft), and is best adapted to cold, oxygen-rich water.
