Cosmocaixa - Hermit crab

At CosmoCaixa you can find two types of hermit crabs: terrestrial and aquatic.

Do you know what kind of hermit crabs are both? This one looks like maybe a species of Coenobita, and the aquatics looks like maybe a Clibanarius, but the exact species?
Labelling in Cosmocaixa (scientific names) was sometimes deficient
Thanks

I don't know and there's no information about the species on the museum. Most of the animals don't have any information panel indicating it's scientific name or common name (I think that only says that are hermit crabs).

Yes Xavi, I know that, and this is the thing that disappointed me more of this - by the other hand - magnific museum. I stayed at Barcelona until eight o'clock more or less, so maybe we could meet again finally if you already finished job.. but well, will be more occasions!

I consulted every kind of list of animals or photo gallery of Cosmocaixa and in everyone says only Coenobita sp. Most well known species is Coenobita perlatus, but maybe this is another...
