Under the Sea: Extraordinary Things Discovered in the Deepest Parts of the Ocean

Who comes up with these marine life names- elementary school kids? The glowing sucker octopus is precisely what his name suggests: he’s bioluminescent and has suckers. However, the ability to produce their own light isn’t typical among octopuses; only a tiny portion of them are bioluminescent. So this guy is a particular rarity.

But here’s the really interesting part about this octopus: his suckers don’t function the way other octopuses do. They can no longer stick to things but have evolved to produce their bioluminescence instead. They aren’t just another pretty face, however. They use their light to lure prey into their open, waiting mouths.
