White-spined sea urchin

P4052086a, 72ppi.jpg

I saw this sea urchin at Grecian Rocks today, in twenty-seven feet of water.  It has all white spines.  I do not recall ever seeing a sea urchin with all white spines before.  Is it albinism, an unusual species, or a normal phase?

White Spine Sea Urchin

Hi Martin,


Not an expert on sea urchins here, but in South East Florida where I do the majority of my diving these urchins with the white spines are pretty common.  Hope this helps.


Thank You
