Nudibranch
This Month in Photo of the Day: Animals
Members of the gastropod class, finger-size nudibranchs live fully exposed, their gills forming tufts on their backs. (Nudibranch means "naked gill," a feature that separates them from other sea slugs.).
See more photographs from the June 2008 feature story "Living Color."
