Blastoid
Buds, blastids - a group of extinct echinoderms, living from the sylvia to the permian. Their bloom reached in carbon. The buds were characterized by a distinct fivefold symmetry of the body. The chalice was built of 13 tiles and set on a stalk. There were 5 breastbags in the cup with numerous thin brachioles. The whole cup was like a rose bud. At the top there was a mouth surrounded by 4 spiraculas and an anthill. These were only marine organisms, leading to a bentonized, sedentary lifestyle.
