Heliocidaris erythrogramma (in situ)
Description The sea urchins inhabit grooves (arrows) in order to better withstand the surging waves. Compared with Hetiocidaris tuberculata this species is not particularly well adopted to this extreme habitat. But here in thecrevices at the bottom of rock canals the animals have developed short, stout spines to minimize water resistance and to protect their test.
