I’ve pressed my face against public aquarium glass more times than I can count, but I’ll never forget the first time I saw a snailfish in the wild. It was during a submersible dive years ago, when a pale little fish fluttered awkwardly across the screen like it hadn’t gotten the memo on how fish are supposed to swim.

That moment stuck with me. So when Monterey Bay Aquarium Research Institute confirmed three new snailfish species, including one called the bumpy snailfish, I couldn’t help but grin. These are the kinds of finds that remind us how little we really know about the dark water below.

An Unexpected Encounter in the Canyon

Back in 2019, MBARI’s remote vehicles captured footage of an unfamiliar pink snailfish hovering above the Monterey Canyon seafloor at more than 10,700 feet down. At the time, it was just a curiosity. Years of imaging, morphological study, and genetic work have now confirmed what divers and aquarists love to hear: this was a brand-new species. They named it the bumpy snailfish (Careproctus colliculi).

Alongside it came two other new members of the family, the dark snailfish (Careproctus yanceyi) and the sleek snailfish (Paraliparis em).

What Sets Them Apart

Snailfishes as a group are already quirky. Soft bodies, big heads, narrow tails, and those funny little belly disks they use to cling onto rocks or even other animals. The bumpy snailfish adds its own flair. It’s pale pink with a rounded head, wide fins, and a body textured almost like fine sandpaper.

The dark snailfish goes the opposite route, pitch black with a horizontal mouth that makes it look permanently unimpressed. Then there’s the sleek snailfish, long and flattened, gliding without the suction disk its relatives carry.

Rare Sightings, Wider Questions

Only one bumpy snailfish specimen has been confirmed so far, a petite female measuring just 3.6 inches. But researchers combing through old expedition footage spotted shapes that may belong to the same species further north, off Oregon.

That hints at a wider range, though no one can say for sure until more evidence surfaces. Deep-sea creatures tend to play hide-and-seek better than anything in a glass tank, and they don’t make it easy for science to pin down their full story.

Why Hobbyists Should Care

You might be wondering what a fish you’ll never see in your home tank has to do with aquarium keeping. For me, the answer lies in perspective. Every time a new deep-sea species is described, it changes how we think about diversity and adaptation. Snailfishes span the globe, from tide pools to the trenches.

The suction disks some carry mirror the way freshwater clingfish or hillstream loaches hold onto glass in aquariums. Even in your tank, you’re watching echoes of strategies that life has been testing for millions of years.

The Bigger Picture

Discoveries like this remind us that Earth’s catalog of life is still far from complete. For aquarists, it’s fuel for curiosity, proof that even humble, unassuming fish families harbor surprises. For researchers, it’s a chance to ask new questions about survival in extreme conditions, energy flow at abyssal depths, and how species carve niches in seemingly inhospitable places.

So while you won’t find a bumpy snailfish in a local pet store, the story should still make you pause at the tank tonight. Watch how your fish dart, graze, or cling, and think about their cousins thousands of feet down. Out there in the canyon, something new is always waiting to be discovered.
