Why Does an Octopus Squirt Ink?

Why Does an Octopus Squirt Ink?

An octopus squirts its inky liquid to escape enemies. The “ink” is a brown fluid produced in the octopus’s body and stored in a special reservoir known as an “ink sac.” Most species of octopus can release a thick cloud of ink.

One of the pigments in the octopus’ ink is melanin (the same pigment that gives our skin and hair color).

When an enemy (such as a hungry moray eel) threatens, the octopus instantly turns a light color and squirts a dark mass of ink into the water. This clouds the enemy’s ability to see.

The ink forms a shape that resembles an octopus and serves as a decoy to hold the enemy’s attention. While the enemy is busy attacking the inky fake, the real octopus scoots away to safety.
