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.
