Taken 2022 22nd January, these are two species displayed for the price of one @evolutionsmuseet being displayed. The common hermit crab (Palaemon adspersus), or eremitkräfta, with its shell covered with snail fur (Hydractinia echinata). In Sweden, these hermits are common along the west coast, being found from tidepools to 140 metre depths. Contrary to the name, all hermits aren't actually crabs, it's simply the perfect body. As for the snail fur, they are colonial hydroids that settle on gastropod shells occupied by hermits on both sides of the north Atlantic, where in Europe it occurs on 'P. adspersus'. #animal #animal #animals #djur #wildlife #natur #naturliv #nature #arthropods #arthropod #kräftdjur #crustacean #crustaceans #hermitcrab #eremitkräftor #animalia #arthropoda #crustacea #decapoda #paguridae #pagurus #pagurusbernhardus #commonhermitcrab #eremitkräfta #cnidaria #anthoathecata #hydractiniidae #hydractinia #hydractiniaechinata #snailfur (at Evolutionsmuseet) https://www.instagram.com/p/CZPvyhEKAyr/?utm_medium=tumblr

Taken the same day as the previous post, this is a common hermit crab (Liocarcinus Pagurus bernhardus), or rödvit eremitkräfta, beyond the preservation jar. Last time I posted a hermit, I mentioned it's not a true crab. They are an example of a phenomena known as carcinisation, first coined by zoologist L. A. Borradaile, which is the morphological evolution of Anomura into crab-like forms. It can seem difficult to tell these 'false crabs' from 'true crabs', but all that's needed is to look at the walking legs; Anomura use three pairs while Brachyura use four. That, and Anomura come in different forms when compared to Brachyura. #animal #animals #djur #wildlife #natur #naturliv #nature #fauna #invertebrate #invertebrates #arthropods #arthropod #kräftdjur #crustacean #crustaceans #hermitcrab #hermitcrabs #eremitkräfta #eremitkräftor #animalia #arthropoda #crustacea #malacostraca #decapoda #anomura #paguridae #pagurus #pagurusbernhardus #commonhermitcrab #rödviteremitkräfta (at Klubbans biologiska station) https://www.instagram.com/p/CeCdtuXKac6/?igshid=NGJjMDIxMWI=
