Did you know?

Hank, a smokey ghost millipede, is a detritivore who spends a lot of time burrowed in the ground. Having existed on our planet for over 400 million years, the structure of millipede burrows can be differentiated from other burrowing organisms to help identify sediment composition and moisture content in the fossil record, providing us with a better understanding of soil health.
