Octopus lay eggs (Just like Hens or Snakes)

65 million years ago octopus also had shell on their back which served as a protection

Octopus makes their home under a cavity or empty space under rock in the sea or a thing like a sea shell And this is known a the “Octopus Den”

North Pacific Giant Octopus is the largest octopus found in the world, it is found in North Pacific ocean

A female octopus has two ovaries for egg production

Shallow water Octopus eggs are usually laid in the Den

Female octopus lays tens of thousand of eggs
Female octopus protects the eggs and remains with them in the Den till they hatch and does not eat anything during this period

Female octopus die as soon the eggs hatch, so there is no protection or upbringing of the young octopus hatchlings by the mother. The male octopus dies just after mating

Seals, Moray eel, Wolf eel and Sharks are the main predators of Octopus
Killer whales also eat giant pacific octopus (which weight around 27kg)

Octopus may try to distract and divert its attacker by gushing through a discharge of water from its funnels, the same technique is also used by the female octopus to keep their eggs clean

Octopus behave very weirdly at the end of their life cycle, they provide easy food to their predators, they come out of their dens or more near to the sea shores to be devoured by sea birds and animals

Blood of a octopus is blue in color

Octopus can bite their prey from their beak and also inject poison in their body from their salivary gland

The life span for the larger species of octopus is 3-4 years; the smaller species of octopus live no longer than 3-6 months

There are around 300 different species of Octopus

The Pacific Giant Octopus has ability to change the color of its body and hence is able to camouflage itself in the surroundings
