Super slow-motion video (like 17 times slower than the naked eye) shows the cuttlefish snag a fish and rake it in with its waiting tentacles.
2. Watch the Video
The full slow-motion video was shot at 500 frames per second. Per second! Watch the cuttlefish feeding as well as changing color.
3. But wait, there’s more!
They change color
Marine scientists believe they use light to blend into or stand out from their surroundings by using tiny sensors all over their skin that help them change color without sending messages to the brain. Exactly how it works is still a mystery.
Some of them are giant
The Australian giant cuttlefish, is the world’s largest cuttlefish species, growing to 50 cm in mantle length and over 10.5 kg (23 lb) in weight.
Some of them are tiny
Dwarf cuttlefish (Sepia bandensis) are small, four-inch relatives of squids and octopuses.
All are threatened by ocean acidification
Ocean acidification caused by increased levels of carbon dioxide in the atmosphere is potentially a threat to all cuttlefish. Studies have shown that under high pCO2 concentrations, cuttlefishes actually lay down a denser cuttlebone which is likely to negatively affect buoyancy regulation.
