The Ghost Octopus Is A Pigment-less, Gelatinous Creature
Scientists found a new species of octopus in February of 2016 off the Hawaiian archipelago, and it's unique for a few reasons. They observed the ghost octopus swimming slowly at about 2.6 miles (4.3 kilometers) deep, much lower than any other octopod (a group of invertebrates that includes octopuses) without fins has even been seen. Other unique features of the octopus: it completely lacks pigment, giving it a very ghost-like appearance, hence the name. And because there's little food in the deep sea, and it takes a lot of energy to build muscles, the ghost octopus has a gelatinous consistency.
