Even spider crabs need baths

Under the supervision of biologist Cathrin Pawlak, fourth-grade students use a bristle brush to clean algae off a spider crab at the Sea Life aquarium in Timmendorfer Strand, Germany, on May 31.

Because algae can hide diseases, the spider crabs are cleaned and given medical checkups regularly.
