Coral Weed is a bright red seaweed that grows on rocks in Irish rockpools. It looks like tiny branching coral or delicate red fingers spreading out. This seaweed provides shelter and food for many small animals like shrimp, snails, and baby fish. Coral Weed helps protect these tiny creatures from predators and strong waves. It also adds color and life to the rockpool, showing that the area is healthy and full of different kinds of life.
