DescriptionGFNMS - purple urchins (27703864430).jpg |
In September 2015, NOAA divers undertook the first diving expedition aboard the R/V Fulmar in the newly expanded Greater Farallones National Marine Sanctuary. They found quite a few species living there, including these purple sea urchins. Usually purple urchins spend their time in cracks and crevices, but these had climbed up and were feeding on denuded stipes of understory kelp. Photo Credit: Steve Lonhart/NOAA |
