chital

The Chital (Axis axis), also known as the Spotted Deer or Axis Deer, is one of the most abundant and recognisable deer species of the Indian subcontinent. Males are distinguished by their elegant three-tined antlers, which can span over a metre, while both sexes display the species' characteristic reddish-brown coat spotted with white — a pattern retained throughout adult life unlike most deer, which lose spots after fawnhood. Chital inhabit grasslands, forests, and forest edges across India, Nepal, Sri Lanka, and Bangladesh, showing a strong preference for areas with access to water and open grazing clearings within or adjacent to woodland. They are highly gregarious, forming large herds in which males, females, and young associate freely outside the rut. Unlike most cervids, chital lack a fixed breeding season, and males are often in velvet or hard antler at varying times of year. They are important prey for tigers and leopards throughout their range and contribute significantly to the ecology of Asian ecosystems. The IUCN lists the species as Not Evaluated under current assessment standards, though it was historically assessed as Least Concern. Chital have been widely introduced outside their native range for hunting and deer farming, with feral populations established in Texas, Hawaii, Australia, and elsewhere.

Common Water Rat

<em>Hydromys chrysogaster</em>, commonly known as the common water rat or rakali, is a semi-aquatic rodent in the family Muridae, native to Australia and New Guinea. It is classified as Least Concern by the IUCN, reflecting its relatively stable population across a broad range of freshwater and estuarine habitats on the Australian continent and associated islands. The species typically inhabits the banks of rivers, lakes, wetlands, and estuaries, where it constructs burrows in streambanks. It is highly adapted for an aquatic lifestyle, with partially webbed hind feet, a flattened head, and a dense waterproof coat. <em>Hydromys chrysogaster</em> is a carnivore, typically feeding on fish, crustaceans, mussels, frogs, and aquatic invertebrates, which it often carries to elevated feeding platforms to consume. The species is nocturnal and crepuscular, most active during early morning and evening hours near the water's edge. Biological traits including average lifespan, body length, and weight remain poorly documented in standardized databases, though adults are generally robust for a rodent, reportedly reaching body lengths of 20–35 cm excluding the tail. Geographic range details for this particular record remain incompletely documented in available data sources. Ecologically, the common water rat is an important apex predator in small-scale freshwater food webs and serves as an indicator species for wetland health in Australian riparian systems.
