According to Moore (1966:81) large Diadema antillarum with some or many 
white or gray spines "...are found in darker and more turbid conditions and 
frequently in caves. In my experience, they seem to be more common in deep 
water around Caribbean reefs than at shallow depths. The spines of 
juveniles are always banded with black and white. Individuals change color 
in response to the intensity of illumination. Animals that are black during 
the day pale at night.
