Grimalditeuthis bonplandi is an inkfish species, from the Chiroteuthidae family. The squid only occurs in salt water and is able to change color. He moves forward by pumping water into his cloak and pushing it out again through the siphon. The squid is a carnivore and its food consists mainly of fish, crabs, lobsters and molluscs that they catch with the suction cups on their grips. However, he is not capable of rapid movements with his tentacles. Well, the kind has two extra long tentacles with protrusions at the end. Observations suggest that these protrusions, which move somewhat shockingly as if they are swimming themselves, are a kind of bait on a "fishing line" to attract prey.
The scientific name of the species was published for the first time by Vérany in 1837.
