World Oceans Day.

The month’s best science images Meet Peinaleopolynoe elvisi, a newly described species of species of deep-sea worm whose iridescent scales evoke glittery-jumpsuit-era musical icon Elvis Presley. Four such stunning species were collected from the bottom of the eastern Pacific Ocean, the Gulf of Mexico and an area near Costa Rica, using a crewed research submarine and remotely operated vehicles. Researchers used DNA sequencing to place all four in the Peinaleopolynoe genus, a group of scale worms distantly related to earthworms.
