Bhitarkanika river system is ruled by a few giant Saltwater crocodiles. This basking crocodile is one of such large crocodiles of about 20 ft. length.  
The area is cris-crossed by numerous creeks and creek-lets and tidal river, and rivulets. The nesting behaviour of mother Saltwater crocodile is different from other two Indian Crocodilian species. She prepares a mound nest in a secluded place by collecting available nesting material which includes aquatic fern species (Acrostischum aureum), Hental (Phonix paludosa), etc. The nesting female crocodile actively guards her nests for about 75 days, until the young crocodiles hatch out for moving into the creeks.
