The Sundarbans are an important habitat for the Bengal tiger (Panthera tigris).[39] The forest also provides habitat for small wild cats such as the jungle cat (Felis chaus), fishing cat (Prionailurus viverrinus), and leopard cat (P. bengalensis).[40] Several predators dwell in the labyrinth of channels, branches, and roots that poke up into the air. This is the only mangrove ecoregion that harbors the Indo-Pacific region's largest terrestrial predator, the Bengal tiger. Unlike in other habitats, tigers live here and swim among the mangrove islands, where they hunt scarce prey such as the chital deer (Axis axis), Indian muntjacs (Muntiacus muntjak), wild boar (Sus scrofa), and Rhesus macaque (Macaca mulatta). It is estimated that there are now 180 Bengal tigers[31] and about 30,000 spotted deer in the area. The tigers regularly attack and kill humans who venture into the forest, with human deaths ranging from 30 to 100 per year.[41]
