Common Haircap

The common haircap, <em>Polytrichum commune</em>, is a moss belonging to the family Polytrichaceae, one of the largest and most structurally complex families within the division Bryophyta. This species is widely distributed across Asia, Europe, North America, and South America, making it one of the most cosmopolitan mosses in the world. <em>Polytrichum commune</em> is typically found in moist to wet habitats including bogs, fens, wet heathlands, and the margins of streams and woodland ponds. It is characterized by its tall, upright gametophytes, which can reach several centimeters in height, and its distinctive star-shaped arrangement of leaves when dry. The species is assessed as Least Concern on the IUCN Red List. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
