Due to their otherworldly appearance and unique characteristics, people often refer to cuttlefish as alien species. Cuttlefish possess large, bulging eyes, undulating tentacles, and a remarkable ability to rapidly change colors and patterns on their skin. These features and their intelligence and complex behaviors give them a mysterious aura.

Their peculiar body structure, including the internal cuttlebone and the ability to rapidly propel themselves using a jet of water, further adds to their alien-like qualities. Thus, comparing to alien species is a way for people to describe cuttlefish’s fascinating and unconventional nature.

Alien indeed. Especially at night, when they come out of nowhere.
