On the east coast of India lies one of the richest biodiversity regions in Southeast Asia. Consider this: it is bounded on the east by the Bay of Bengal and its 480 km coastline extends from the Subarnarekha River in West Bengal to the Bahuda River in Andhra Pradesh. It has not one but 7 major river deltas of varied sizes and shapes formed by the rivers Subarnarekha, Budhabalanga, Baitarani, Bramhani, Mahanadi, Rushikulya and Bahuda.
This region has 5 major morphological zones - the coastal plains, the
middle mountainous and highlands region, the central plateaus, the
western rolling uplands and major flood plains. This region is Orissa -
home to a high diversity of marine and reptilian life.
The coast of Orissa forms a highly complex yet dynamic eco-system,
comprising of a myriad of wetlands, deltas, mangroves, and mudflats-
truly an ecologist's paradise! These factors make the coastline of
Orissa an ideal habitat for many species like the estuarine crocodile,
fresh and brackish water terrapins, dolphins, porpoises and the
endangered sea turtles. There are four species of sea turtles (out of
the seven in the world) found in Orissa - the Olive Ridley, the
Hawksbill, the Leatherback and the Green Sea Turtle.
