Discovery of Three New Deep-Sea Snailfish Species Off California

Marine biologists have identified three new species of deep-sea snailfish from the family Liparidae, discovered at depths exceeding 10,000 feet off the coast of California. The findings, published in the journal *Ichthyology and Herpetology*, detail the bumpy snailfish (Careproctus colliculi), the dark snailfish (Careproctus yanceyi), and the sleek snailfish (Paraliparis em). This research was conducted by a collaborative team from the Monterey Bay Aquarium Research Institute (MBARI), the State University of New York at Geneseo, the University of Montana, and the University of Hawai’i at Manoa.

The bumpy snailfish was first observed in 2019 during an expedition using the remotely operated vehicle (ROV) Doc Ricketts, which descended to approximately 10,722 feet in Monterey Canyon. The dark and sleek snailfish were collected using the submersible Alvin at a depth of about 13,451 feet. Researchers utilized advanced imaging technologies, including micro-computed tomography (micro-CT) and DNA sequencing, to confirm the uniqueness of these species and to analyze their physical characteristics.

The bumpy snailfish is characterized by its pink color, large head, and bumpy texture. The dark snailfish features a fully black body and a rounded head, while the sleek snailfish is distinguished by its long, compressed body and absence of a suction disk. The bumpy snailfish is particularly notable as it is the only confirmed observation of its kind, raising questions about its population and distribution.

This discovery underscores the significant biodiversity present in the deep ocean, which remains largely unexplored. Mackenzie Gerringer, an associate professor at SUNY Geneseo, emphasized the importance of curiosity and exploration in understanding marine life, stating, “Our discovery of not one, but three, new species of snailfishes is a reminder of how much we have yet to learn about life on Earth.”

While the discovery is celebrated, some marine biologists argue that the focus on newly discovered species should not overshadow the urgent need for conservation efforts in the deep sea. Concerns have been raised about the impact of climate change and deep-sea mining on these fragile ecosystems.

The research team expressed excitement over the findings, highlighting the role of advanced technology in uncovering marine biodiversity. The study's lead author, Mackenzie Gerringer, noted, “The deep sea is home to an incredible diversity of organisms and a truly beautiful array of adaptations,” reinforcing the need for continued exploration and research in these environments.

Future research efforts will aim to locate additional specimens of the bumpy snailfish to better understand its ecological role and distribution. The ongoing study of snailfish taxonomy is crucial for enhancing our knowledge of marine biodiversity and informing conservation strategies.
