白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

Coastal beach sandmat

Euphorbia mesembryanthemifolia, the coastal beach sandmat, is a prostrate, mat-forming succulent herb in the family Euphorbiaceae adapted to coastal sand dune and beach margins in the Caribbean basin, with native occurrences in Cuba, Colombia, and adjacent tropical American coastlines. The species is particularly well adapted to harsh coastal conditions including salt spray, intense solar radiation, shifting sands, and periodic flooding, forming low, spreading mats directly on beach sand and foredune systems. Its small, thick, succulent leaves resemble those of ice plants (Mesembryanthemum) in the family Aizoaceae, a resemblance captured in the specific epithet. Like all euphorbias, it contains a toxic milky latex that deters herbivory. The cyathia, or characteristic euphorbia pseudoflowers, attract small insects that pollinate the plants. Euphorbia mesembryanthemifolia is classified as Least Concern by the IUCN, though Caribbean coastal habitats face significant ongoing threats from sea-level rise, increased storm surge associated with intensifying hurricanes, beach tourism infrastructure development, and coastal stabilization that removes the natural dynamism these specialist plants require to persist and disperse along shorelines.
