Comb-footed spider

<em>Parasteatoda tabulata</em> is an arachnid in the family Theridiidae, commonly grouped with comb-footed spiders. It has been recorded from Europe and the United States, indicating a broad distribution across temperate regions of the Northern Hemisphere. Like other members of the family Theridiidae, <em>P. tabulata</em> constructs irregular, tangled cobwebs in sheltered locations such as corners of buildings, under eaves, rock crevices, and dense vegetation. The species uses its characteristically comb-like hind tarsal setae to manipulate silk and wrap prey. It is a generalist predator of small insects and other arthropods that become ensnared in its web. Members of this family are small spiders, generally spending their adult lives in close association with their webs. The species has not been formally assessed by the IUCN, and specific quantitative biological trait data are not available in the current record.

Red-billed Duck

Red-billed Duck (Anas erythrorhyncha) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.
