Colombian Robber Frog

<em>Pristimantis erythropleura</em>, commonly known as the Colombian Robber Frog, is an amphibian species belonging to the genus <em>Pristimantis</em> within the family Craugastoridae, the largest genus of vertebrates by species count globally. This species is assessed as Least Concern by major conservation bodies, indicating stable populations without immediate elevated extinction risk. It has been documented in Colombia, where it inhabits freshwater-associated environments, moist forests, and wetland habitats typical of neotropical Andean and foothill ecosystems. Pristimantis frogs are direct-developing, bypassing a free-living tadpole stage entirely, with fully formed froglets hatching directly from terrestrially deposited eggs. This reproductive strategy confers independence from standing water for reproduction, enabling colonization of a wide range of humid forest microhabitats. Dietary information specific to this species has not been documented, though pristimantid frogs typically consume a variety of small invertebrates. Biological traits of this species remain poorly documented in the scientific literature. Continued forest conservation in Colombia is important for maintaining habitat availability for <em>Pristimantis erythropleura</em>.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
