Common Hermit Crab (Pagurus bernhardus)

Also known as the soldier crab, the common hermit crab is a species of pagurid hermit crab which is distributed along most of Europe’s Atlantic coasts. Common hermit crabs are typically seen in pools on the upper to lower shore regions in rock/tide pools. Common hermit crabs chiefly detritivores but they will also scavenge and filter feed if necessary. In typical hermit crab fashion P. bernhardus will use the shells of gastropod species, like Littorina sp. and Buccinum sp. for protection.

The first image is a phantom view, and the second one is an animated gif, both showing what the hermit crab’s body looks like inside the shell.

(Apparently animated gifs is the cool thing to do, so I thought I’d see how it can enhance scientific illustration.)

Save the sea squirts! Wait, what?

Think of ten animals that you know are endangered – go on, we’ll wait. Now, cross out every animal on that list that has fur, hair, feathers, or scales. Do you have many left on that list? Do you have any left at all? - @pagurus

Although invertebrates make up the majority of the animal kingdom, they are often overlooked in conservation efforts. Will we ever look beyond the mighty, the cute, and the magnificent?

Illustrated as the final instalment in a series covering endangered animals, published on Earth Archives.

pagurus  asked:

Heya, I recently found out that a cat has decided to raise her kittens in our garden shed. I don't know how old they are, but they aren't walking yet. I've moved all sharp objects out of the shed and tried to make it a bit easier for the mother to get to her kittens, but I don't really know if there is anything else I should do besides leaving them alone?

Leaving them alone is a good call. 

Depending on where you live and what the mentality is around it, you could trap them and foster them for a shelter organization that helps lower the numbers of feral cats. That normally works with TNR for the mother and keeping the babies until they can be adopted out.

Curled Octopus (Eledone cirrhosa)

Also known as the Lesser Octopus or the Horned Octopus, the curled octopus is a species of octopus that inhabits areas in the sublittoral zone in the Atlantic Ocean, English Channel, North Sea and the Mediterranean Sea. Like some other octopuses E. cirrhosa feeds mainly on crabs and other crustaceans, feeding mainly on Homarus gammarus, Nephrops norvegicus, and Cancer pagurus.

Totally popular!

One of the most common snails in tide pools and the intertidal zone from Vancouver, B.C. to Baja California is the black turban snail (Chlorostoma funebralis, formerly Tegula funebralisI).

It often carries around stubborn company that hitchhike atop its shell, including the hooked slipper snail (Crepidula adunca) and the black limpet (Lottia asmi).

Aptly named for its color and whorled shell, this small invertebrate has been recorded living up to an impressive 30 years – but that’s if it can survive its reputation as a tasty treat for sea otters, rock crabs, sea stars and even humans.

Its empty shell is prime real estate for a hermit crab. Two species in particular (Pagurus samuelis and P. granosimanus) actually prefer these shells, which make up 70 to 90 percent of their homes.

You can see the black turban snail in many of our Ocean’s Edge exhibits, especially the Kelp Forest and rocky shore exhibits. You might also find them in our touch pools, but it might just be the shell – now occupied by a hermit crab.

Have you ever seen a hermit crab swap out its shell for a new one? These resourceful little crustaceans have long, spirally curved bodies that are soft and vulnerable, which is why they protect themselves by carrying empty seashells (or sometimes other objects) into which they can completely retract when in danger or just feeling a little shy. But as hermit crabs grow they require larger shells to accommodate their bigger bodies.

Bournemouth, UK-based photographer Steve Guntrip captured this awesome video of his pet European hermit crab (Pagurus bernhardus) changing shells inside its aquarium. This is a very vulnerable moment for these animals, so the transition is very quick, but Guntrip replays the cute little crab’s relocation in slow motion, so we get a nice good look at how the crab emerges from its old home and then backs into its swanky new one.
