Object Description

A water bear (tardigrade), Hypsibius dujardini. This is an adult, about 200 microns long, in a ventral view, imaged by scanning electron microscopy. Tardigrades were chosen as a model for studying how development evolves because they are relatives of arthropods (including Drosophila) and nematodes (including C. elegans).
