Here is a interview with marine biologists in New Zealand who have used glass shells to help study hermit crabs.  The crabs voluntarily moved into the hand-blown glass shells with 7-10 days of the glass shells being added to the tanks.

The interview aired two hours ago, and is only on the TV3 website at the moment.  If I see it on YouTube I’ll embed it here.

A Hermit Crab in a Glass Shell– surprisingly, the most popular post on my blog.

Hermit Crab in a Glass Shell – Origin – the follow-up post to satisfy my curiosity about where this popular yet controversial photo came from. (Read the comments to the original post, I’ve deleted the abusive ones,  and other sites featuring the same photo have much longer and more negative comment threads.)

I don’t even like crabs all that much!  When my biology class studied a common mubcrab in my final year of school, I got my eight year old brother to come in after school and help me with an experiment because I wasn’t going to touch the crabs!

I’m just not big on animals – except birds.  Birds are awesome! Fish are cool too, but they are tricky to keep as pets. Birds are prettier and less prone to floating upside down in a bowl.  (Except for the time I found one of my canaries dead in the water trough.)
