Common Cotton-Grass

<em>Eriophorum angustifolium</em>, commonly known as common cotton grass or many-stalked cottongrass, is a perennial sedge in the family Cyperaceae. It is distributed across peatlands, bogs, fens, and wet moorlands of Europe and North America, where it is often a dominant and ecologically significant species. Common cotton grass is easily recognized by its distinctive fluffy white seed heads, which resemble balls of cotton and appear conspicuously across boggy landscapes in late spring and summer. These cotton-like structures are modified perianth bristles that aid in wind dispersal of seeds. The species plays a vital role in peatland ecosystems as a peat-forming plant and provides food and nesting material for various wetland birds. It is assessed as Vulnerable on the IUCN Red List, reflecting ongoing habitat loss due to peatland drainage, agricultural conversion, and climate change. Biological traits of this species remain poorly documented in the scientific literature.

Orca común

El mayor miembro de la familia de los delfínidos, la orca (Orcinus orca) puede alcanzar hasta 9 metros de longitud y 6 toneladas de peso, y se encuentra en todos los océanos desde el Ártico hasta el Antártico. Es un depredador apex que vive en grupos matrilineales con dialectos distintos, estrategias de caza y tradiciones culturales que difieren entre poblaciones. Algunas poblaciones se especializan en peces, otras en mamíferos marinos. Sin depredadores naturales, las orcas ocupan la cima de todas las cadenas tróficas marinas que habitan.
