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.
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.
