Green sea urchin

The term "green sea urchin" is used in French to refer to several species of sea urchins (spiny, spherical marine echinoderms), based on their color. Their skeleton is rounded and lacks the long spines typical of sea urchins. Instead, they have thick, flat plates covering their bodies. Their dominant color is an olive green, which can vary in intensity depending on the species, as can their size.

The shells are sold individually: each piece is unique and, due to natural variations in shape, color and pattern, the model shipped will be chosen randomly from the available specimens.
