Urchin, Zebra White Spine

Product Description

Product Description

The Banded sea urchin has a slightly oval test (shell), reaching a diameter of about 5_cm._Like almost all the_Diadematidae_(but it is in_Echinothrix calamaris_that it is most obvious) it has two different sets of spines, shorter and slender closed spines which are going from yellow to dark (through brown) in colour and can deliver a nasty sting, and longer and thicker spines that are often banded with light and dark colour (but sometimes all dark or all white), and reaching 10 to 15_cm in length._These radiolas can be blunt, and are hollow. The spines are grouped so as to let appear five naked zones on the central part of the test, in a star pattern (called "iridophores"): this pattern can be colored, often in blue._The anal papilla is big, more or less translucent and very obvious on the aborale face; it is generally whitish and speckled with black and white dots, circled by a ring of visual receptors that grant it a rudimentary vision.
