The coral community in Hoi Ha Wan Marine Park is one of the best colonies in Hong Kong. More than 60 species of hard coral and 120 species of reef fish were recorded. This is one of the reasons why it is designated as a Marine Park!

You can't survive by drinking sea water ¡V it's too salty. The same is true for nearly all plants, except mangroves and a few others. Mangroves are now known to be extraordinarily valuable for coastline protection (from tsunamis such as the Asian Tsunami in Dec. 2004) as well as providing a rich feeding ground and shelter for young fish to grow.

A rocky shore is an inter-tidal area along the coastline where solid rock predominates. Barnacles and bivalves like mussels can survive by sticking themselves to the rock surface with some of the stickiest glues in the natural world. These animals survive pounding waves, daily wetting and drying with the tide and many other animals such as birds trying to eat the soft flesh inside their hard shells.

A sandy shore, which is also known as a beach, is a good recreational place for humans, and also home of wildlife such as bivalves, crabs, sea urchins, fish and egrets!
