What deep-sea creature, found nearly three miles beneath the ocean surface, became an internet star after appearing in a February 2026 YouTube video?

The deep-sea creature that captivated the internet in February 2026 is a chiton, a fascinating type of marine mollusk. This particular species, discovered nearly three miles beneath the ocean surface in the Izu-Ogasawara Trench, gained widespread attention after being featured in a YouTube video. The unusual appearance and habitat of this deep-sea dweller quickly made it a viral sensation, drawing global interest to the mysteries of the abyssal plain.

Following its surge in popularity, scientists from the Senckenberg Ocean Species Alliance, in collaboration with science communicator Ze Frank, launched a public naming competition for the newly identified creature. Over 8,000 suggestions poured in from around the world. The winning name chosen was *Ferreiraella populi*, a scientific designation that fittingly means "of the people," acknowledging the massive public engagement in its discovery and recognition.

Chitons are unique invertebrates, often described as resembling a cross between a snail and a beetle. Unlike most mollusks with a single shell, chitons are characterized by eight overlapping shell plates that provide protection and allow them to flex over uneven surfaces or even curl into a ball when threatened. The *Ferreiraella populi* specifically thrives on sunken wood in the deep sea and possesses a remarkable iron-clad radula, a rasping tongue used for feeding. This deep-sea specialist provides valuable insight into the poorly understood ecosystems that exist thousands of meters below the surface.
