Habitat Ecology and Intraspecific Variations in Estuarine Crocodile Crocodylus porosus Schneider, 1801 (Reptilia: Archosauria: Eusuchia: Crocodylia: Crocodylidae) in Two Contrasting Estuarine Ecosystems of Eastern India

A comparative study of estuarine crocodile (Crocodylus porosus) populations in Bhitarkanika National Park and the Sundarbans Biosphere Reserve reveals significant intraspecific variations shaped by habitat connectivity. The research, conducted during March-April 2026, identified 52 individuals across both sites, highlighting differences in population density, size distribution, trophic resources, and territorial behavior. Bhitarkanika's semi-isolated ecosystem exhibited higher competition due to restricted resources, whereas the Sundarbans' dynamic, marine-connected environment supported broader trophic niches and reduced conflict. These findings underscore the critical role of habitat connectivity in crocodilian ecology and conservation outcomes.
