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.

águia-real

Entre as aves de rapina mais poderosas e amplamente distribuídas do mundo, as águias-reais têm envergaduras que chegam a 2,2 metros e habitam terrenos montanhosos em todo o Hemisfério Norte. Caçadoras aéreas supremas, usam voo planado e mergulhos íngremes a velocidades superiores a 200 km/h para capturar coelhos, lebres, esquilos terrestres e ocasionalmente cervos jovens e raposas. Em muitas culturas, foram centrais nas tradições de falcoaria que abrangem milênios.
