The Amazing Octopus

By  | July 10, 2017 | Filed under: News

An octopus is a cephalopod mollusc of the order Octopoda. It has two eyes and four pairs of arms and, like other cephalopods, it is bilaterally symmetric. An octopus has a beak, with its mouth at the center point of the arms.

Octopuses are considered the most intelligent of all invertebrates. Scientific studies are increasingly confirming that they are sentient creatures.

A few Facts about the Octopus:

As active predators they need to explore, understand and remember their environment and the behaviour of other animals.  Studies have shown that octopuses learn easily, including learning by observation of another octopus.  And did you know….They are the first invertebrates to be seen using tools, such as using coconut shells to hide from potential predators and using rocks and jets of water in a way that could be classified as tool use.

Using a network of pigment cells and specialized muscles in its skin, the common octopus can almost instantaneously match the colors, patterns, and even textures of its surroundings. Predators such as sharks, eels, and dolphins swim by without even noticing it.

Two pump blood through each of the two gills, while the third pumps blood through the body.  They also have beaklike jaws that can deliver a nasty bite, and venomous saliva, used mainly for subduing prey.
