Do mollusks squirt ink

Yes, certain mollusks, particularly cephalopods like squids and octopuses, can squirt ink as a defense mechanism. This ink is released into the water to create a cloud that helps them evade predators by obscuring their escape. The ink contains melanin and other compounds that can also irritate the eyes or respiratory systems of attackers. However, not all mollusks produce ink; it is primarily a characteristic of cephalopods.
