Zonaria (alga)
Zonaria is a genus of thalloid brown alga comprising approximately 12 species. Specimens can reach around 25 cm in size, all of which exhibit a characteristic semi-circular growth pattern which produces distinct alternating patterns of darker and lighter tissue akin to tree rings. Zonaria produces tetraspores.
