An octopus squirts its black ink through a specialized structure called the ink sac, which is located near its digestive system. When the octopus feels threatened, it contracts the muscles around the ink sac, forcing the ink out through a siphon. This ink is composed of melanin and serves as a defense mechanism, creating a cloud that can obscure the octopus's escape. The ink can also irritate predators' eyes, providing the octopus with a chance to flee.
