Range

Distributed across Chile, Portugal, Taiwan, and Venezuela. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Colorful Pericote

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Basking shark

The world's largest fish, whale sharks can exceed 12 meters and 20 tonnes, inhabiting tropical and warm temperate oceans worldwide. Despite their massive size, they are harmless filter feeders, consuming plankton, fish eggs, and small fish by swimming open-mouthed through prey-dense water. They undertake vast seasonal migrations following plankton blooms. Endangered due to fishing, boat strikes, and the live fin trade, with population declining by approximately 50% over the past 75 years.

Colorful Pericote

<em>Auliscomys pictus</em>, the colorful pericote, is a rodent in the family Cricetidae within the diverse South American assemblage of sigmodontine mice. This species is assessed as Least Concern by the IUCN and is associated with diverse terrestrial and aquatic ecosystems. Pericotes of the genus <em>Auliscomys</em> are typically inhabitants of high-altitude Andean environments, including puna grasslands, rocky slopes, and shrublands above the treeline. The colourful pelage suggested by the common name may reflect variation between the dorsal and ventral fur colouration typical of many Andean small mammals, providing countershading against open sky and substrate backgrounds. Like other small Andean rodents, <em>Auliscomys pictus</em> is likely omnivorous to herbivorous in diet, consuming seeds, plant material, and occasionally invertebrates. These rodents serve as important prey items for Andean raptors, foxes, and mustelids, occupying a central trophic position in high-altitude ecosystems. Limited survey data from specific countries have been recorded for this species. Biological traits of this species remain poorly documented in the scientific literature.
