Octopuses are fascinating marine critters. Octopus is a Greek word that translates as “eight-footed.” There are about 200 kinds of octopuses, and they all inhabit in oceans worldwide, often near coral reefs. Octopuses are classified as invertebrates, which means they lack bones. As a result, when an octopus is plucked from the water, it loses its shape.

Octopus Facts 

1. All octopuses have a mantle-shaped head surrounded by eight tentacle-like limbs. Their heads contain all of their critical organs.

2. Their color as well as size are controlled by the environment in which they live. Those living in colder water will be significantly larger than those living in tropical (warm) water.

3. Their only hard feature is their beak, which resembles a parrot’s beak. They consume food with their beaks.

4. They hunt crabs, crayfish, mollusks, etc. using powerful suction cups (240 per tentacle).

5. They have three hearts and blue blood.

6. While they are invertebrates, they have an extremely developed neural system and are capable of learning new skills. Several experiments demonstrated that they are capable of solving problems and discriminating between forms and patterns. They are capable of both short-term and long-term memory development.

7. Due to their highly developed neurological system, some believe that octopuses experience pain during surgery, necessitating the administration of anesthetic before to surgery.
