Scientists have discovered how two marine creatures are able to rapidly "switch" their colours - from transparent to reddish brown. The species, an octopus and a squid, use their adaptable camouflage to cope with changing light conditions in the deep ocean. The creatures' skins respond light that deep-sea predators produce to illuminate their prey.

A new report records 17,650 species living below 656 feet, the point where sunlight ceases. The findings were the latest update on a 10-year census of marine life.
