Decadal status of Acanthaster planci (Linnaeus, 1758) along the coral reef habitat of Andaman and Nicobar Islands

The coral reef habitats have been facing insightful threats from natural and anthropogenic sources across the world; while are creating major ecological pressure with maximum percentage of devastation to entire ecosystems. Acanthaster planci (L) or Crown-of-Thorns Sea star (CoTS) is known as potential predator corals can disrupt ecosystem their outbreaks within much-stipulated time.  CoTS reported all areas Andaman Nicobar Islands a mean density 0.71/ hectare range 1.08±0.33 0.40±0.18 per between North & Middle Nicobar, respectively. distributional pattern signifies that crest represents occurrence in comparison slop top; an inversely proportional relationship be seen individuals depth gradients.

No observation on population was made during decadal study period intrinsically noted limit level CoTS. presence predators like used take leading role balancing ecology denotes healthy this archipelago.
