Transcript of Octopus
Primarily eat crabs, lobster, clams, craw fish, mollusks, or crustaceans gathered for night time foraging
They will also eat shrimp, sea snails, plankton, small sharks, fish, and sometimes even other octopus.
Octopus's do not migrate or hibernate
Generally not aggressive
Octopus's will attack when provoked and female are more prone to attack when they are taking care of their eggs
If threatened, they will either flee and run away or try to fight back
Octopus's will try to disturb the intruder rather than hurt them
Octopus's are capable of crushing or hurting other animals
During a hunt, octopus's move along the ocean floor using their great eye sight
Then, they use their sensors located in their suction cups, which allow it to detect taste, smell and texture.
Once the prey is found, the octopus will sneak up, and rapidly grasp the victim then go back to it's den and eat it privately
Some will use "mating games"
Others will just "bump into" each other, mate briefly, then go about their separate lives
If needed, octopus's will try the "sneaker approach" - octopus will approach guarded female by scuttling them from hiding places and using their camouflage on the sea floor, then they will approach the female
This tactic takes twice as long as a normal approach
Females lay eggs and tend them by cleaning and ventilating them
Soon after the eggs hatch, the female dies
The lifespan is approximately 8-10 months, but if the octopus remains several months in plankton. they can survive up to 2 years.
Octopus's generally will not form a group to increase their chance of group survival
They use three tactics for defense: ink sacs, camouflage, and automising limbs.
Ink sacs: Eject ink out at the predators
Camouflage: use special skin cells called, chromatophores.
Automise limbs: crawling arm serves as a distraction to the predator
Octopus's communicate by rapid changes in skin color and patterns through the nervous control
They use their chromatophores to change their color. The center of each chromatophore contains an elastic sac full of pigment, which may be colored black, brown, orange, red or yellow.
