Priotrochatella is a genus of land snails with an operculum, terrestrial gastropod mollusks in the family Helicinidae.Priotroachatella occur on calcareous rocks and in caves in the same rocks on Cuban islands - they are critically endangered because of the exploitation of the marble quarries that form their habitat.

many of the large land snails with the ‘classic’ snail appearance that people see in north america are introduced garden dwelling species, but N. albolabris is a native species that’s most at home deep in moist forests where it feeds mainly on fungi.
A #zebrashark “poses” next to his ID sign in the Tropical Reef tank at the Minnesota Zoo. Zebra sharks are actually only striped as babies - as juveniles grow into adulthood, the stripes fade out to spots. Even though he’s big, this #shark isn’t a potential predator for any of the other fish in this tank; zebra sharks prefer #mollusks and small #crustaceans for dinner. #reeftank #coralreef #aquarium #zooanimals #zoo #minnesotazoo (at Minnesota Zoo) https://www.instagram.com/p/BoR_dDRgyVs/?utm_source=ig_tumblr_share&igshid=105iacnd6hcve
If you’re gearing up for your Trivia Tuesday, here’s some good ones for you: Solander’s Trivia and the Coffee Bean Trivia!
Trivia are minuscule, beautiful sea snails that parade about in search of morsels to munch. Their ornate shells are kept clear by spectacularly decorated bodies that lick the shell clean of grime and growth.
In this post, Solander’s Trivia Pusula solandri are the first two images, the Coffee Bean Trivia Pseudopusula californiana the last two. Solander’s is typically found south of Point Conception, while the Coffee Bean Trivia covers much of the California coastline.
It’s a bird, it’s a plane, it’s…a sea slug! The spanish dancer nudibranch brings a new level of excitement to diving with slugs. Where most nudis amble slowly over their environment, the spanish dancer can actively swim by twisting its body and pumping water with its large, flowing “skirt.” The fluffy tuft on its back end are actually gills, and give the nudibranch its name - nudi meaning naked, and branch meaning gills! Found at @reefdivers on Instagram.
New research led by scientists at the American Museum of Natural History and Yale shows that the oldest ancestors of the group of animals that includes octopuses and vampire squids had not eight but 10 arms. The study, which describes a new species of vampyropod based on a 328-million-year-old fossil that had not been previously described, pushes back the age of the group by nearly 82 million years. The details are published today in the journal Nature Communications.
“This is the first and only known vampyropod to possess 10 functional appendages,” said lead author Christopher Whalen, a postdoctoral researcher in the Museum’s Division of Paleontology and a National Science Foundation postdoctoral fellow in Yale’s Department of Earth & Planetary Sciences.
Whalen and coauthor Neil Landman, a curator emeritusin the Museum’s Division of Paleontology, identified the fossil specimen as a completely new genus and species that dates to about 328 million years old, making it the oldest known vampyropod and extending the fossil record of the group by about 82 million years. In the new study, they also describe its 10 arms—all with preserved suckers—corroborating previous scientific arguments that the common ancestor of vampyropods had 10 arms as well.

I have some live pothos and English ivy in there, as well as some various mosses; hoping they hold up well with the humidity. Still need to get a small food dish, but I cannot WAIT for the snails to arrive!!

Ever wonder what an octopus feels like? Well, they’re slightly squishy, but also quite strong and muscley. They also somehow feel velvety and slippery at the same time. Their suction cups are really strong and grippy!
Cephalopods, including octopuses, are mollusks, close cousins to slugs, snails, mussels and scallops. An octopus is a little like a normal mollusk turned inside-out! It has a soft body, and its shell has been reduced to two small plates where its head muscles anchor, plus a powerful, parrot-like beak.
So what you’re saying is that they feel like a sea hare that pumps iron
