Urchins – Pencil and Collector
There are spiky urchins aplenty on the reef. Less common are the pencil urchins, obviously named because their spikes are the diameter of pencils. I almost passed this collector urchin except that my flashlight picked up the brilliant color. Later the book showed and named it for me. Yes, they pick up debris and cover themselves, hence the name, collector. As I said I thought it was plant not animal the first time I looked.
