Three new species of snailfish show there's still plenty of mystery surrounding the deep sea.

======================================================================
In 2019, scientists spotted something strange thousands of meters below the ocean surface. There, they filmed a pink bumpy blob with cartoonishly big eyes and more pectoral fin-rays than you could shake a stick at. Now, they’ve been able to confirm that this was a new-to-science species. It’s a snailfish, and better yet, it’s one of three new-to-science species described in a new study.
There are over 400 species of snailfish across the globe, some of which are the deepest-dwelling fish known to science. Now, we have three more to add to the roster: the bumpy snailfish, Careproctus colliculi, which is pinkish in color, meanwhile the other two new species – the dark snailfish, C. yanceyi, and sleek snailfish, Paraliparis em – are both black.
“Two of these are black snailfishes collected on the same dive by the submersible Alvin,” said study lead and Associate Professor of Biology Mackenzie Gerringer from SUNY Geneseo to IFLScience. “As I looked more closely at the specimens, I was very surprised at how different these two individuals were.”
"These were not an adult and a juvenile of the same species, they are very different both morphologically and genetically. These two species were discovered at Station M, an incredibly valuable research site with decades of exploration and time series data. The fact that two undescribed species of snailfishes were collected from the same place, on the same dive, at one of the better studied parts of the deep sea in the world highlights how much we still have to learn about our planet.”

All three snailfish were found thousands of meters below the ocean surface, but thankfully, through their photos and videos, the team of scientists working with the Monterey Bay Research Institute and Aquarium (MBARI) has brought them to the surface for us all to enjoy.
As you can see, the bumpy snailfish is remarkably adorable as deep-sea creatures go, looking very different to the dark and sleek snailfish. It might seem odd to have such drastically different colorations among snailfish living in the same region, but when you’re this far from the surface, color doesn’t count for much.
“At these depths, there is no sunlight, so color becomes less important for hiding,” said study lead Mackenzie Gerringer from SUNY Geneseo to IFLScience. “These snailfishes are likely sensing one another and their environment using other means, particularly by picking up vibrations in the water and by smelling and tasting their surroundings.”
“Many fishes can actually ‘taste’ with their fin rays, it’s likely that these species are using those dextrous pectoral fins to sense. Although there is no sunlight at these depths, there are some flashes of light from bioluminescence. We don’t yet know if or how much these species are using vision, this would be a great area for future research.”

==============================================================
Speaking of fin rays, the bumpy snailfish are particularly impressive. Across its body it has 22, and we were curious to know what so many fin rays could actually do. Turns out, they come with many benefits.
“The beautiful video from MBARI’s remotely operated vehicle shows how actively and gracefully this fish is controlling these pectoral fin rays,” said Gerringer. “These rays are very important for swimming, particularly for turning, but also play a role in how the fish senses the surrounding environment.”
Snailfishes belong to the family Liparidae, and they can inhabit drastically different habitats. Some live in shallow tidal pools while others lurk at the deepest depths of the ocean, but they tend to share a fairly similar body plan consisting of a big head and jelly-like body. Some hitchhike on larger animals using suction pads on their bellies, while others cling to rocks and curl up like a snail.
And say hello to the sleek snailfish, Paraliparis em. Image courtesy of © 2019 MBARI Gerringer’s extensive work into their taxonomy, functional morphology, and physiology has brought up closer to understanding how it is they’re able to survive under such crushing pressure, where the water is so cold and there is no light, but it’s nice to know there are still snailfishes to be discovered out there in the wild.
“Needless to say, I love snailfishes!” said Gerringer. “I think they are incredible, and working with them is a joy.”
“We often think of deep-sea environments as being harsh or extreme because of how different the pressures, temperatures, light, and other conditions are from what we experience. But for many organisms, the deep sea—the largest living space on our planet—is home. To me, finding species that seem so fragile thriving in these habitats highlights the beauty of the deep sea and our responsibility to understand and protect these incredible ecosystems.”
The study is published in the journal Ichthyology & Herpetology.

If not much can be seen down there, why do these fish even have eyes?
Dude needs to get drunk then laid......
Almost as cute as the axolotl.
She’s the kind of enthusiast who often makes great discoveries or comes up with great inventions.
For one thing, they can detect bio luminescence from other fish:

Thanks.
Uhhhh, okay
Less drama please. I on the other hand would not like to die for this to say nothing of the salmon mousse.
People incapable of deep interest in a subject haven’t often come up with groundbreaking discoveries or achievements. It could be said that many scientists and inventors have actually been obsessed.
LIFE, LIFE, LIFE writ large is so much more adaptable to a changing earth than all the alarmists could ever imagine. They think humans can destroy the living earth by our own daily activities. “Change”, yes, but every living thing imposes itself on the landscape of earth and everything it encounters accepts it or adapts to the conditions it presents. LIFE writ large goes on.
The alarmists think, in error, that when LIFE has to adapt to some human activity that LIFE writ large is being destroyed. Not true.
Does that include you and I? Admittedly, I haven't invented anything. How about you?
I’m too much of a dilettante. But I have great admiration for people who care so much about a subject that they make important discoveries and inventions. They tend to be very interesting people, too.
You sound like a Lake St. Clair fisherman.....
It was filmed and theres a video. Duh!
She would die for a snailfish? I don’t even think those people in the plastic sub wanted to die for the Titanic.
Yes, but so far, no Muskie. If I ever do hook one, I hope I don’t panic. I’m not out there very often.
