A Deep-Sea Discovery Reveals 24 New Species and a Rare Scientific Breakthrough
Somewhere between Hawai’i and Mexico, in a stretch of Pacific Ocean floor so vast and dark that more than 90% of its species don’t even have names yet, researchers just discovered 24 creatures nobody knew existed — including one so strange it required an entirely new classification of life to describe it.
The findings, published in a ZooKeys special issue, came out of a region called the Clarion-Clipperton Zone, or CCZ — roughly 6 million square kilometers of deep seabed that remains one of the least understood ecosystems on Earth.
A Discovery Scientists Say They’ll “Always Remember”
The 24 new species are all amphipods — small crustaceans that include predators and scavengers — spread across 10 different families. But the real headline is what the team didn’t expect to find: a brand-new superfamily, Mirabestioidea, along with a new family called Mirabestiidae and new genera Mirabestia and Pseudolepechinella. The researchers also recorded the deepest known occurrences for several genera and produced the first molecular barcodes for some rare species.
Tammy Horton, one of the study’s lead researchers, said: “To find a new superfamily is incredibly exciting, and very rarely happens so this is a discovery we will all remember.”
She added: “With more than 90% of species in the CCZ still unnamed, each species described is a vital step towards improving our understanding of this fascinating ecosystem.”
16 Researchers, One Week, 24 New Species
The work happened during a 2024 taxonomy workshop at the University of Lodz in Poland, where 16 researchers from institutions around the world gathered to tackle the ambitious task of identifying amphipod species from the CCZ. The team included scientists from the National Oceanography Centre, the Natural History Museum in London, the Canadian Museum of Nature, NIWA, the University of Hamburg, Senckenberg, and the University Museum of Bergen.
The project is part of the International Seabed Authority Sustainable Seabed Knowledge Initiative and a broader effort called the “One Thousand Reasons” project, which aims to describe 1,000 new species by the end of the decade.
Co-lead Anna Jażdżewska said: “This was a truly collaborative process that allowed us to achieve the ambitious goal of describing more than 20 species new to science within a year – something that would not have been possible if each of us worked independently.”
She added: “The team’s findings provide information that is crucial for future conservation and policy decisions, and it highlights how important it is for this work to continue.”
At the current pace of about 25 species per year, researchers estimate amphipods in the eastern CCZ could be nearly fully cataloged within the next decade.
The Names Tell Their Own Stories
What scientists name new species often reveals as much personality as the discovery itself. Several were named after team members — Byblis hortonae, Thrombasia ania, and Byblisoides jazdzewskae. Horton named one, Mirabestia maisie, after her daughter.
One species, Lepidepecreum myla, was named after a video game character, described as “are just little arthropods trying to survive in total darkness.”
Then there’s Pseudolepechinella apricity, named for an obscure English word meaning the warmth of the winter sun. Horton explained why: “Apricity means the feeling of the warmth of the winter sun, and it is one of my favorite words. It was very apt to use during the workshop as we discussed our findings in the warmth of the February sun amid the snow of the Polish winter in Lodz. It was certainly fitting to also use it for one of our amphipod discoveries.”
She added: “We came together as research colleagues, but the spirit of collaboration and shared experience shone through, so it was important to recognize that in our work.”
Another species, Eperopeus vermiculatus, was named in honor of the World Register of Marine Species — a quiet nod to the infrastructure that makes cataloging deep-sea biodiversity possible in the first place.
