rockpool
Shore's natural aquarium
A rockpool is a small pool of seawater left among rocks when the tide goes out.
These shallow pools form natural habitats for crabs, anemones, small fish, and other marine life, making them popular spots for children to explore at the beach: We spent hours peering into rockpools.
Also spelled as two words: rock pool.
