In the ever-evolving arms race of the deep sea, camouflage is the name of the game.
Other than making yourself attractive to a potential mate, most sea creatures rate being invisible to predators as a high priority.

TheÂ Japetella heathi octopus and the Onychoteuthis banksii squid share the ability to change from a transparent state to an opaque red colour.
