Like all echinoderms, the sea star Asterias forbesi uses fluid-filled tube feet (seen here) for locomotion and feeding. The "spiny skin" common to echinoderms is also visible (purple areas). Asterias forbesi is common in the intertidal and subtidal regions of Southern New England. This photograph was taken during a field trip to Nahant, MA., a site visited by students in Marine Biology and Ecology of Atlantic Shores.

A control (C57BL/6; +/+) and two HPS (Hermansky-Pudlak Syndrome) mutant mice. Pale ear (HPS-1) and light ear (HPS-4) are autosomal recessive traits on inbred strain C57BL/6 (ep/ep and le/le, respectively). Note the hypopigmentation of the pinnae of both mutants. While these mutants share the same phenotype, they are inherited independently and both genes encode novel proteins that may function in vesicle trafficking.
