Glass houses for Hermit crabs

So this rather beautiful thing has just been brought to my attention.

Staff at the aquarium were intrigued how hermit crabs make their homes in discarded snail shells, it was often asked “How do they manage to squeeze their entire body into such a small space?” or “Wouldn’t it be cool to see inside?”

Enlisting the expertise of University of Otago scientific glass blower Anne Ryan, the aquarium wanted to replicate a snail shell that would be suitable home for a hermit crab. With the hermit crab taking up residence, it is now clearly visible how they twist their abdomen around the central column of the shell and the well-adapted tip of the abdomen clasps strongly to hold it in place.

Centre Manager, Tessa Mills said “The staff are so excited. This is going to provide us with new teaching opportunities and will be really fantastic for the public to come and view.” More glass shells have been requested, so soon there may be a whole cast of hermit crabs living in glass shells at Portobello.
