Eurhinosaurus is a cool species of ichthyosaur that had a long snout like a marlin and probably held the same niche.

Art is mine.

Yareta (Azorella compacta) in Bolivia (elevation of 14,000 ft.).

This may look like a moss, but it isnt! This is a broad-leafed plant in the carrot family, Apiaceae.

These plants can grow to bve over 3000 years old. This large specimen may be over 1000 years old.

I LOVE THIS FREAK SO MUCH

I think I stumbled upon some kind of ichthyological forbidden knowledge. Opened up a book of names that were never meant to be read.

You've probably heard of "can-opener smoothdream", right? It's practically a meme by now.

But the thing is, it's a deep-sea fish. And deep-sea fish have historically not had English names because nobody drops them into the conversation over a hot cuppa. Sure, there's generic stuff like hatchetfish and barreleye, but when you want to refer to the actual fish you're probably saying such euphonious phrases as Diretmus argenteus, Sternoptyx diaphana, or maybe even Opisthoproctus soleatus.

So whence "can-opener smoothdream"? Certainly no non-ichthyologist has ever used that name. It's not even a direct translation of the scientific name Chaenophryne longiceps - that would be "long-headed gape-toad". Which to me is even cooler than "can-opener smoothdream".

But I digress. The "dream" bit comes from the anglerfish family Oneirodidae, from oneiros, "dream", because those marvelous fishes look like they came out of a dream (Pietsch, 2009).

Note that Pietsch (2009), more or less the anglerfish bible, uses English names at the genus level only. So Chaenophryne is the smoothhead dreamers genus but no mention is made of "can-opener smoothdreams". So no luck there.

Wikipedia, root cause of a lot of misinformation, has this to say.

"Longhead dreamer" is a far more accurate name. And in fact, despite Wikipedia prioritizing "can-opener smoothdream" (because it's funny?), the links listed use "longhead dreamer" and "smoothhead dreamer" as the name and "can-opener smoothdream" as an alternative.

So. Again. Where did "can-opener smoothdream" come from?

The answer, as it turns out, lies with McAllister (1990).

In the book A List of the Fishes of Canada, ichthyologist D. E. McAllister sought out to list every single fish known to Canadian waters, providing both an English and a French name.

And when there wasn't an English name, like for most deep-sea fishes, he arbitrarily gave them a name. And his names "differ in many instances from the widely accepted names" (Holm, 1998)

This had varying results. This is his name for one of the netdevil anglerfishes.

The humpback anglerfish or blackdevil anglerfish becomes a werewolf (????).

This one is just confusing.

The white-spotted lanternfish or Rafinesque's lanternfish instead becomes...

And most embarrassingly, the Mediterranean spiderfish gets saddled with something that "violates the tenet of good taste" (Holm, 1998).

This then is the original source of "can-opener smoothdream". It was invented by an ichthyologist in 1990, and has seen little to no use outside of how bizarre the name is.

Maybe McAllister's goofier names will catch on. Who knows? They certainly aren't very popular in the scientific community though.

shrimps are cool but i am not a shrimp. when i shrimp over the table for too long, my back starts to hurt. i stand up on my human legs and stretch my human body every hour. sometimes i wish i was a shrimp.

I just don’t get it. How can our society act so goddamned normal about seahorses. How can anybody so casually accept that that’s a fish???

This is one of nature’s most anatomically perverse of all beasts. A FISH, like a carp or a bass or a beta is a fish, but it bent its body straight up only to bend its head permanently back down. It stretched its skull into a pipe. It tapered its tail like a lizard, specifically like a chameleon. It can also move its eyes independently by the way, you know, like a chameleon. Fun fact, it can change color to express its mood, like you know whatever does that. It doesn’t properly swim anymore. It buzzes its few remaining fins like an insect’s wings to float itself around at a snail’s pace. It lives its whole life clinging to coral branches or seaweed, which means it decided to become a “tree dweller” in an environment where gravity didn’t even matter anyway. The males get pregnant. They make noises at each other by rubbing some of their neck bones together. Every day, EVERY DAY a mated pair does a little dance and a little neck bone song so they remember which two seahorses they were. They’re a beautiful precious obscenity. Nothing so adorable ever made such a strong case against a logical creator.

They have as little skin and meat as they could get away with. Their skeleton is almost all they are.

This thing is one of the most successful hunters on the planet. Because their mouth is fused shut, except for the tip, they can create a powerful suction force in front of that one little opening in order to draw in prey. 

Lions have a 20-30% success rate on their hunts, depending on daytime and if they’re in a group. Great white sharks, anywhere from 40% to 80%, depending on the size and skill of the individual. Dragonflies, which are one of the most successful terrestrial hunters, can hit about 80-85%. Seahorses? 90% success rate, sometimes more. Only a fraction of their prey escapes that powerful vacuum. They’re incredibly precise. 

If you touch them, they feel hard, because of the skeleton underneath their skin. Their tails are being studied to make coiling bridges, because of how strong that interlocked structure is. Different species range in size from over a foot long, to barely an inch. 

Behold: not just a fish, but a wildly successful predator! 

horsey

don’t forget their majestic cousins the sea dragons! these are the leafy and weedy sea dragons

and the newest seahorse family member, discovered in 2015, the ruby sea dragon ❤️

Yeah that’s when someone tried to straighten the seahorse back out and it still didn’t look right. The more they bent and mushed it in their hands to look like a fish again the worse they fucked it up until finally they just left it and walked off and hoped nobody would ask who did this

(I love them so much)

Oh, so it’s actually the ruby sea dragon on a string! Got it.

i doubt that someone hasn’t already brought them up in another reblog but anyways. don’t forget about pipefish! relatives of seahorses which are literally as physically close to a worm on a string as any real animal could get, imo
