Habitat & Geographic Range

Anchovy-Eater

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate grasslands and steppes, among 9 distinct biome types spanning the Indomalayan and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

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

Common Leaf-litter Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Mexico.

Anchovy-Eater

The largest predatory fish on Earth, great white sharks can reach 6 meters and 2,000 kg, inhabiting cool coastal and offshore waters in all major oceans. Apex predators employing ambush attacks from below, primarily on marine mammals, large fish, and seabirds. Despite their fearsome reputation, unprovoked attacks on humans are extremely rare. Vulnerable, with populations declining from finning, bycatch, and targeted fishing despite legal protections in many jurisdictions.

Common Leaf-litter Frog

The Common Leaf-litter Frog (<em>Craugastor loki</em>) is a direct-developing frog in the family Craugastoridae, classified as Least Concern on the IUCN Red List. It is native to Mexico, where it typically inhabits freshwater habitats, moist forests, and wetlands in tropical and subtropical lowland and montane regions. As a member of the genus Craugastor, this species undergoes direct development, with eggs hatching as miniature froglets rather than passing through a free-living aquatic tadpole stage. This reproductive strategy reduces dependence on standing water and allows the species to colonize a variety of moist terrestrial microhabitats, including forest floor leaf litter, mossy logs, and stream banks. The Common Leaf-litter Frog is cryptically colored, blending into its leaf litter surroundings for camouflage against predators. Its Least Concern status reflects relatively stable populations within its Mexican range. Biological traits of this species remain poorly documented in the scientific literature.
