Colorful Sea Slugs Steal “Weapons” to Attack Predators

Sea slugs, also known as nudibranchs, are colorful animals that use their bright appearance as a warning for the predators. They may move slowly, but they have a brilliant defense mechanism.

Sea slugs can “steal weapons” from another creature – hydroid. Hydroid looks like seaweed, but it’s actually a relative of jellyfish that’s covered in venomous stingers. When a sea slug feels threatened, it deploys these stingers to the enemy.
