Researchers recently made an exciting discovery in the deep Pacific Ocean off California’s coast: three new species of snailfish. This finding highlights the rich diversity of life hidden beneath the sea, a place still largely unexplored. The study was published in the journal BioOne.
The standout among the trio is the bubblegum-pink “bumpy snailfish,” officially named Careproctus colliculi. The research team found it at 10,722 feet deep in Monterey Canyon. The other two species, the sleek black snailfish (Paraliparis em) and the dark snailfish (Careproctus yanceyi), were collected from 13,513 feet below the ocean surface at Station M, a well-known research site. This teamwork, using advanced submersibles and DNA analysis, reflects just how much we still don’t know about our oceans.
Mackenzie Gerringer, the lead biologist on the study, shared her thoughts on the significance of these findings:
“The fact that two undescribed species were collected from the same site on the same dive shows how much we still have to learn about our planet.”
Combining DNA sequencing with physical examinations, researchers were able to officially identify these new species and gain insight into the evolution of snailfish in such extreme environments.
Meet the Bumpy Snailfish
The bumpy snailfish is not just unique in its appearance but also showcases fascinating adaptations. With its rounded head and soft body, it stands out with its vibrant bubblegum-pink color. Gerringer calls it “pretty adorable,” injecting a bit of whimsy into this scientific work. Johanna Weston, a deep ocean ecologist at the Woods Hole Oceanographic Institution, describes snailfish as “beautiful” and notes their colorful range, which includes purples and blues.
These bright colors and rounded features serve practical purposes. They help with camouflage, pressure adaptation, and evading predators in the dark depths of the ocean. The bumpy texture of its skin may enhance sensory perception, helping the fish navigate its environment.
Uncovering Deep-Sea Diversity
The discovery of two black snailfish species was tricky; they looked very similar. Oceanographer Brett Woodworth explained this “cryptic” nature:
“Their external morphologies are similar, but we could distinguish them through genetic analysis.”
This highlights the hidden diversity within our oceans, even in areas that have been studied extensively. By merging genetic information with morphology, scientists are piecing together how these creatures have adapted and thrived in challenging conditions.
Honoring Contributions in Science
Scientific naming often pays tribute to those who have advanced our understanding of a field. For instance, the dark snailfish (C. yanceyi) honors Paul Yancey, a notable deep-sea biologist. The sleek snailfish is named for its discovery site, Station M. The interesting names underscore the collaborative spirit of deep-sea exploration and honor the efforts of the scientists dedicated to uncovering the ocean’s mysteries.
As we discover more about the deep sea, it’s clear that it’s a world full of surprises—both in terms of life and the technology that allows us to explore it. The findings from this research emphasize the need for continued exploration and understanding of our planet’s largest and least-known habitat.

These discoveries remind us that our oceans hold secrets yet to be uncovered, making every dive a potential journey into the unknown.
