I have some friends living in a tank in my lab - Giant African Land Snails
. Although ownership of GALs is illegal in the US, they make popular pets in the UK. Easy to care for, quite long-lived (an average of five years) and easy to breed they are also popular in schools.
Every so often, one dies. It's no big deal, they're only snails after all, and they lay hundreds of eggs a year if they're reasonably-well looked after. The only problem is what to do with the corpse.
I have found that the easiest way to deal with the body is to bury it for a few weeks and let minibeasts do their work. After that, it's only a matter of washing the shell out with plenty of hot water and a peg on your nose.
But what do you do with a slowly-growing pile of large shells?
