Interesting Facts about Octopuses

Updated on April 25, 2010

Interesting Octopus Facts

Here are some really interesting Facts about octopuses.....

An octopus species known as the mimic octopus can actually impersonate other creatures.

Female blanket octopuses are 40,000 times heavier and 100 times larger than the male blanket octopuses. Females grow about 6.6 feet in length while males grow 0.9 inches. Also, the males are there only to mate, after which they die.

All octopuses have three hearts.

They have no bones and will not be able to maintain their shape out of water.

The color of their blood is blue.

They have a very good eyesight but can not hear.

Blue-ringed octopuses are one of the most venomous creatures on this earth. They are small in size but have the ability to kill 26 human beings within a few minutes. They can also squirt their venom on their prey when it is at some distance.

All octopuses can change their color.

Sometimes octopuses may shed an arm to escape a predator.

When threatened or provoked, the blue-ringed octopus will quickly change its color to bright yellow with blue rings on it.

Dumbo octopuses have paired fins that look like elephant ears. Also, they do not have a particular breeding season. They are deep sea creatures.

Blue-ringed octopuses are found in Pacific ocean.

Their main predators are sharks, dolphins and conger eels, while they commonly prey upon crabs and mollusks.

Blanket octopuses defend themselves against predators by tentacles of Portuguese man-of-war jellyfish.

Female big blue octopuses are known to eat males after copulation.
