Underwater Life
The coastline of Cemlyn includes areas of shingle, sand and exposed rocky shore. These provide habitats for a variety of marine life including sea-anemones, crabs, prawns, blennies, butterfish, winkles, whelks, limpets, coastal lichens and a range of seaweeds. e.g. kelp.

The lagoon, with its changing mixture of fresh and salt water is a challenging environment, but Grey Mullet and Eels thrive in the brackish conditions. In fact Cemlyn is one of the top sites for specialised saline lagoon wildlife including shrimps and molluscs, and waterplants like Tassel Pondweed.
