MARC - Marine aquarium cum regional centre - is a major tourist attraction for all Digha visitors. It has the largest inbuilt aquarium in India. The aquarium has three kinds of creatures: species of conservative importance, 'local and curious' species and freshwater species.
These species include sea anemones, lobsters, sharks, rays, butterfly fishes, sea snakes, horse shoe crabs and a bunch of other not-so-commonly-heard-of organisms.
