New study quantifies the impacts of mining on deep sea organisms. Researchers found:
🪱number of organisms decreased by 37% in mining tracks
⚖️number of species decreased by 32% in mining tracks, making the remaining community more unbalanced

You know, I'm a predator guy through and through (basically all we've got in the mesopelagic!) but filter feeders can look sooooo cool when they wanna
Skeleton shrimp: superior snackers
This amphipod in the family Caprellidae, has feather-like setae line several of their 18 appendages for collecting food — amphipod translates to “feet on all sides” in Greek.

YESSSS look at THAT! Very reasonable candidate for weirdest fish alive
From 1,750–2,000 m deep, we collected one of the rarest deepsea fishes out there: a one-jaw eel (family Monognathidae). Only ~100 specimens of this group are known worldwide and we hold the largest collection (~46), most just a few inches long… The one we collected though, 6 inches or 154 mm!

Zanclus were a very hard species to reject from last year’s Fishmas list of monospecific families, but I think I made the right choice.
Also: if you’ve never been to a reef habitat, I cannot overstate how *nuts* it feels to walk along the shore and see tropical fish vibing in the water next to you.

Lilipuna Pier, part whatever: a bunch of little guys.
These are kihikihi or moorish idols (Zanclus cornutus). They're cool for a bunch of reasons but one of them is that they're the only species in their family and they can be found basically everywhere in the Indo-Pacific except the Red Sea.

Sooo cool - first footage of a live arrowtail I've ever seen. That erect first dorsal fin is such a giveaway that this is some sort of cod relative - pelagic gadiforms are all such freaks. Beautiful velvety dark colouration as well!

Cool how despite having massive caudal and pelvic fins all the motion seems to be coming from the tiny second dorsal, anal, and pectoral fins
Hey little bebeh Ornate Ghost Pipefish - what are you doing out here in the middle of the ocean in the middle of the night, drifting around with the plankton? Not something I’d expect to see out here!

Fun new paper documenting deep-sea fishes off Puerto Rico. The paper documents some interesting observations, including how diversity changes with depth & even how cusk eels are an important but understudied part of abyssal & hadal communities. 🦑🐟🌊

Now that is incredibly cool. Prototaxites, already one of the weirdest fossils, just got weirder!
20 / 23 We looked to other groups of complex multicellular organisms and found that Prototaxites also couldn’t be placed there, suggesting that Prototaxites is best considered as a member of an independent and now entirely extinct lineage of eukaryotes.

Flies are so cool man, and the thing you don't learn until you really start paying attention is that all the ones that have horrific lifestyles are the coolest looking.

Really committing to the siphonophore mimicry (if indeed that is the function of the elaborately decorated gut extension)
When it comes to my Aliens Collection, the weirder the better - and few fish are weirder than the larval-stage #Lamprogrammus #cuskeel

Having said this midwater fish are beautiful and if you disagree you simply have no taste 💅
The lesson to learn from the blobfish is not "all animals are actually beautiful in their context", it's "all animals are deserving of love, respect, and protection regardless of whether they are aesthetically pleasing to us".

One of my pet peeves (which the OP deftly sidesteps) is people insisting that the blobfish is only ugly when decompressed. Look, I love it with all my heart, but at no point is the blobfish pretty! At its best it looks like a naked molerat inflated with a bicycle pump.
Last repost. What a Blobfish looks like when it’s underwater and alive is considerably less funny than internet meme blobfish. Like seeing an actor who normally does panto dames doing his shopping in February.

Went down a mini rabbithole last night and this morning but does anyone remember this cool observation from a NOAA cruise in 2016 (can't believe it was a decade ago...). Thousands of spherical, sedimentary pellets across the seafloor, in some places drifted like snow - tentatively IDed as Gromia?

Ok off-the-cuff comment which I probably don't fully believe but are tarpon the best "boring" fish? Like are they the coolest thing which doesn't really innovate on the form (silver, fish shaped, standard number and positioning of fins)?
