Mysterious 'unidentified squid' with horns appears in the Gulf of Mexico

What the devil is that? This demonic looking 'vampire' squid was spotted for the first time in the Gulf of Mexico. Whatever it is, you won't have to worry about it washing up on during your next beach holiday. It was discovered by a deep-sea research vessel, 4000m below the ocean basin.

The NOAA's Okeanos Explorer is just days into its latest investigation of the deep-water areas of the Gulf of Mexico.

But, the team has already stumbled upon some truly remarkable creatures thousands of feet beneath the surface.

The most striking of the bunch – at least, so far – may be one squid with a set of particularly pointy horns and a billowing red cape. These pictures surfaced in a features on the Mail Online, which was quick to pick out these devilish features.

Researchers spotted the mysterious blood red cephalopod during a dive this morning, and they don't quite know what to call it.

While some have suggested it could be a vampire squid, which are known for their somewhat menacing appearance, the researchers haven't yet put a name to the crimson-colored creature.

For the time being, they've referred to it simply as an 'unidentified squid.'

'We have seen several different squid species so far on this dive,' the team noted on Twitter.

In addition to the stunning red squid, the NOAA team has come across sea stars, crabs, comb jellies, and a mesmerising skate in the depths of the Gulf of Mexico.

The mission, which began on April 11, will continue through May 3 to investigate the habitats and mysterious shipwrecks thousands of feet down in the Gulf of Mexico Basin.

It is the last expedition in the region before the researchers head back to the East Coast, the NOAA says.

The Gulf of Mexico is home to countless underwater marvels, from coral and sponge communities to undersea canyons and mud volcanoes.

And, there are scores of unknown shipwrecks lying on the seafloor.

The team will be studying the region around the clock, with daytime dives using the remotely operated vehicle (ROV), and overnight mapping to reveal new insight on the 'deep-water areas in important, yet largely unknown, U.S. waters.'

The NOAA wrapped up the first of its three Gulf of Mexico expeditions at the end of last year.

And, the mission came to a close with another unusual find.

The remotely operated vehicle exploring the region captured a look at a bizarre sea cucumber as it fed on the seafloor – and, with its oddly truncated body and wing-like protrusions, it's come to be known as the 'headless chicken monster.'

The so-called headless chicken monster, a sea cucumber called Enypniastes eximia, was spotted during Dive 11 of the NOAA Okeanos mission in the Gulf of Mexico.

Before finishing the 2017 leg of the mission, the team also captured footage of deep-sea crabs, sea spiders, metallic-looking squid, and a colony of pink 'ice worms.'
