Sunday Sketch: Purple Sea Urchins

Purple sea urchins (Strongylocentrotus purpuratus), believe it or not, are actually closely related to humans as revealed by genomic sequencing.  Sea urchins, in general, have a range of lifespans, and purple sea urchins have one of the highest with a maximum of more than 50 years!  This makes sea urchins relevant for a variety of aging research.
