Filmmaker and biologist Shane Siers captured the cryptic creature in Puerto Galera, Philippines.
But don’t be fooled by its beauty-this flashy cephalopod could be deadly.
The flamboyant cuttlefish performs a hypnotic dance across the ocean floor. Unlike many human toddlers, they can even pass the marshmallow test : A 2021 study found cuttlefish can will eat less food earlier if they know they will be rewarded with shrimp, their favorite treat, if they wait. They can count and can remember what, where, and when they last ate a memory trait once believed to be unique to humans. IntelligenceĬuttlefish have a large brain-to-body size ratio-among the biggest of all invertebrates-which makes them incredibly intelligent. The cuttlefish’s beak, located at the base of its arms, is sharp enough to break hard crab shells. These predators feed on fish, crabs, prawns, smaller cuttlefish, and shrimp, using extendable tentacles to grab prey which they immobilize with a toxic bite. They can also move using jet propulsion: filling their body cavities with water then forcefully squirting it out to propel themselves backward. By adding different amounts of liquid or gas into tiny holes within this structure, these animals can change their buoyancy, making them float up or down. The mantle-the area behind the eyes which contains the cuttlefish’s internal organs-is surrounded by a fringe-like fin that flaps in a rippling motion for maneuvering.Ĭuttlefish control buoyancy using an internal shell called the cuttlebone. These cephalopods (which means “head foot”) have eight arms and two long tentacles attached directly to their head. While most live in shallow waters, some species can be found at depths of more than 3,000 feet. The more than 120 different species of cuttlefish are usually solitary animals and can be found in oceans all around the world. Despite being colorblind, cuttlefish also have highly sophisticated color-changing abilities. These fascinating creatures can count, exert self-control, and have numerous wily tactics to evade predators, including creating their own body double from a cloud of ink. Despite their name, cuttlefish are not fish but intelligent invertebrates related to the octopus, squid, and nautilus.
