10 GIFs Of Deep-Sea Creatures Encountering A Sub | Popular Science

Never-before-seen images from a recent expedition to the ocean floor

For the past three weeks, we've been following an incredible livestream of the bottom of the Gulf of Mexico, filmed from a submersible operated by researchers aboard the Okeanos Explorer. The expedition, led by the National Oceanic and Atmospheric Administration, ended this week. Using the sub's high-def camera, the scientists captured footage of parts of the ocean floor never before seen by humans, including ancient shipwrecks, unidentified species, and rare geology.

We'll have much more coverage of this expedition next week, so stay tuned. But in the meantime, enjoy these animated GIFs of deep-ocean creatures that wound up in the sub's LED beams—many of them likely experiencing bright light for the first time.

This is a dumbo octopus using its ear-like fins to swim. According to NOAA, this coiled-tentacle posture has never before been witnessed in this species.

Here's another view of the same dumbo octopus.

This was an exciting moment. A bright red creature—a Humboldt squid?—swam right past the sub's cameras before disappearing into the darkness.

Here's a gorgeous sea cucumber.

A rat tail fish suddenly realizes it has an audience.

A jellyfish swims in a current.

Hello, fish. Behold human technology.

A little red shrimp swims away from the sub.

At first, the researchers couldn't tell what this creature was, only that it was rapidly fleeing the ROV. Turns out to have been some kind of ray or skate.
