🌴 Descripcion de diferentes piezas de historia natural las mas del ramo maritimo: . En La Havana: En la Imprenta de la Capitania General, 1787.. Original source Image description: Historical black-and-white illustration from 1787 depicting three different species of Caribbean crabs. Each crab is detailed with distinct claw shapes, leg positions, and shell textures. The first crab, labeled “Cangrejo Gallo, choco fig. 1,” has a smooth, rounded shell. The second, “fig. 2,” shows a patterned, spotted shell with elongated claws. The third, “Cangrejo de Arrecife fig. 3,” has a rougher-textured shell and robust claws. The image is a natural history plate printed in Havana, focusing on maritime fauna of the Caribbean region, emphasizing anatomical features for scientific observation.

in her blankie!!!
have you guys heard about the greenland shark. some crazy shit happening there.
they are sexually mature at ONE HUNDRED AND FIFTY YEARS OLD.
their (live!) young gestate for. wait for it. eight to eighteen (??) YEARS. can have up to 10 at a time. good grief.
longest lifespan of any vertebrate, up to five hundred years
toxic flesh
has giant eyes but is usually blind because of a weird little crustacean that's evolved to live on and eat their eyes. this doesn't seem to bother them much.
lives in deep cold water and has the lowest swim speed and tail-beat frequency for its size across all fish species. just generally lives life in extreme slow motion
largest genome of any shark
eats everything including moose and polar bears
ma'am you are delightfully strange and I'm privileged to share a planet with you
this post prompted me to refresh my memory on Greenland Shark Facts and this detail about how they feed goes so hard
just vacuuming up their unsuspecting prey. whole !
Good news good news good news! Recent research suggests the eye parasites do NOT blind them!
Dorota Skowronska-Krawczyk sits in her office, eyes fixed on the computer monitor in front of her. "You see it move its eye," says the UC Ir
I <3 you a normal amount Greenland sharks
Seal appreciation post, those guys are my favorite animals and I love them so much.
They have done nothing wrong, ever. (I will not accept it)

Hello, glad your requests are open again! Can I please get some worms, of various kinds? Thanks so much in advance!
You and I need to have a serious talk about the Nereid worms!!!

And because you are a platinum level member, and we love ALL polychaetes here, here is a green Sand Mason Worm for you as well...

species with funny binomials discovered this year
Zig (genus de novo) zag (a Malagasy legless skink related to Paracontias), March 2026. Zig is the first new genus of Malagasy skinks discovered since the 19th century, so this is quite notable! New species discoveries are common, new genus discoveries are much rarer. Some new Scincidae genera have been named recently in the form of splits from other (wastebasket taxon) genera, however, discovering a completely unknown highly divergent lineage like this is a rarity. Zig zag is a special little boop noodle.
Solenostomus snuffleupagus (sp. nov), May 2026 (literally, study was released a week ago), a new species of ghost pipefish, named for its fuzzy appearance bearing resemblance to Mr. Snuffleupagus from Sesame Street (pictured above). The genus Solenostomus contains six other species of ghost pipefishes. However S. snuffleupagus is so highly divergent in appearance, that when it was spotted in 2001 it was immediately known to be strange. It took 25 years of searching the Great Barrier Reef to officially find & scientifically describe this bizarre fish.
S. paradoxus, the type species of Solenostomus.
S. leptosoma, another species, to make clear the typical appearance of a ghost pipefish and why S. snuffleupagus is distinctive.
Though not all species were sequenced, genome sequencing suggests that S. snuffleupagus is the most evolutionary divergent of all Solenostomus (Maroubra, a syngnathid true pipefish, is used as the outgroup).
For context, what Solenostomus is:
Solenostomus is a monotypic genus (the only genus in its family) in the family Solenostomidae. They comprise the sister taxon to the Syngnathidae (the true pipefishes, seadragons, and kin, which contains the famous seahorse Hippocampus). Unfortunately, in Solenostomus, males do not get pregnant (the only thing that would have made S. snuffleupagus even more incredible), but they are closely related to the true pipefishes (all of which exhibit male pregnancy).
Those are two incredible discoveries within just the span of two months, here's to more wonderful scientific names!

A new specimen of the Middle Triassic Ichthyosaur, Besanosaurus, has been described with an in-utero fetus revealed through X-ray imaging. The fetus is oriented tail-first, something seen more often in advanced icthyosaurs!

This Pride Month, we’re celebrating the beauty of diversity above and below the surface. The ocean is full of vibrant life in every color imaginable. It reminds us that nature thrives when everyone has space to belong.
Environmental advocacy and the LGBTQ+ rights movement share a common purpose: protecting vulnerable communities, caring for the spaces we all call home, and creating a world where we all can flourish. Our world is brightest when people can live authentically, love freely, and be embraced for who they are. From rainbow reefs to shimmering tides, diversity makes our blue planet stronger, healthier, and more inspiring.
Here’s to protecting our ocean, uplifting every voice, and honoring the colorful communities that make this world so wonderful.
