Common Pond Frog

<em>Fejervarya vittigera</em>, the common pond frog, is a dicroglossid frog in the family Dicroglossidae, adapted to freshwater and wetland habitats including rice paddies, ponds, marshes, streams, and irrigated agricultural fields. It is typically a robust, medium-sized frog with a brown or olive-grey dorsum marked with longitudinal ridges and variable patterns, well suited for camouflage in its aquatic and semi-aquatic environments. The species is broadly distributed across South and Southeast Asia, favouring lowland areas with permanent or seasonal water availability. <em>Fejervarya vittigera</em> is carnivorous, typically feeding on invertebrates including insects, worms, and small crustaceans encountered near the water's edge or within aquatic vegetation. It is assessed as Least Concern on the IUCN Red List, with populations generally considered stable across its wide range, supported by its tolerance of modified habitats such as rice paddies. Biological traits such as average adult lifespan, precise body dimensions, body mass, and comprehensive dietary data across its geographic range remain poorly documented in the scientific literature. The species may face localised pressures from pesticide use in agricultural areas and habitat drainage.

Common Seal

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.
