A Ghost Shark, a Glass Castle, and 1,121 New Ocean Neighbors

The deep ocean just got a lot more crowded on paper. In May 2026, the Nippon Foundation–Nekton Ocean Census announced that scientists had described 1,121 species new to science in a single year — a 54% jump over the previous annual pace of discovery. Across 13 expeditions and 9 species-identification workshops, researchers pulled back the curtain on creatures that have been living out of sight, in some cases for millions of years.

Meet the new arrivals

The roster reads like a bestiary. From 6,575 meters down came a new deep-sea ghost shark — a pale, wing-finned relative of sharks and rays gliding through the Coral Sea. On a volcanic seamount off Japan, biologists found a symbiotic bristle worm that makes its home inside a "glass castle": the crystalline silica chambers of a glass sponge. There were also new corals, crabs, shrimps, sea urchins, and anemones, each one a small correction to how little we actually know.

The ocean covers 71% of the planet, yet scientists estimate we have formally named only about 10% of the species living in it.

Why counting matters

This isn't stamp-collecting. Naming a species is the first step to protecting it — a creature without a name is nearly impossible to write into a conservation plan or a fishing regulation. Historically it has taken an average of 14 years for a newly collected marine specimen to be formally described. The Ocean Census was built to collapse that timeline, fast-tracking discovery so policy can keep pace with what lives where.

Every new species also fills in the map of how the ocean actually works. A single glass-sponge community can shelter dozens of dependent animals; a ghost shark signals a food web humming along in the dark. Knowing these connections helps us predict which places are irreplaceable and worth safeguarding first.

Discovery is a reason for hope

It's easy to read ocean news as a running tally of loss. But 1,121 new species in one year is a different kind of headline — a reminder that the sea is still gloriously full, still surprising, still worth fighting for. You can't fall in love with what you've never met, and this is a very good year for meeting the neighbors.

That's exactly the spark Fantastic Oceans works to light. When coastal communities understand the astonishing variety of life just offshore, the ocean stops being an abstraction and becomes a place worth defending. Curiosity is contagious — and it leads straight to conscious choices, from the seafood on our plates to the plastic we keep out of the water. The more of the ocean we come to know, the more of it we'll choose to protect. There are still, by every honest estimate, hundreds of thousands of neighbors left to meet.
