Present status of coral reefs in Gulf of Mannar Islands

Abstract

Coral reefs are the most diverse marine ecosystems in the world. Typically they contain number of specialised species representing almost all groups of marine animals. One of the reasons for the great diversity of life in coral reef is the diversified habitats they offer. The great number of holes and crevices in the reef provides abundant shelter for fishes and invertebrates. Coral reefs are also important nurseries and are thus a peculiar store house and repository of various animals.
