Coloma's Noble-Rainfrog

<em>Noblella coloma</em>, commonly known as Coloma's Noble-Rainfrog, is an amphibian species belonging to the genus <em>Noblella</em> within the family Craugastoridae. This species is classified as Data Deficient, indicating that insufficient information is available to assess its conservation status accurately, and that it may be at risk but cannot be categorized without further data. It inhabits freshwater-associated environments, moist forests, and wetland habitats typical of neotropical regions. Rain frogs in this family are direct-developing amphibians, meaning they bypass a free-living tadpole stage and hatch as miniature froglets directly from terrestrially deposited eggs. This life history strategy is well-suited to humid forest floors and leaf litter microhabitats where moisture is available. Specific country-level distributional data are not recorded in current documentation. Dietary information specific to this species has not been documented; however, small frogs of this type typically prey on small invertebrates. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient classification underscores the need for targeted field surveys to determine population size and distribution.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
