coastal hook moss

Sanionia orthothecioides, the coastal hook moss, is a pleurocarpous moss in the family Scorpidiaceae distributed across Arctic and subarctic coastal regions of Norway, Sweden, and adjacent high-latitude environments. Mosses in the genus Sanionia are characteristic components of moist Arctic tundra, snowbed communities, and coastal habitats where they form extensive carpets in areas of persistent soil moisture near snowmelt or coastal spray. Sanionia orthothecioides grows in dense cushions or mats on wet rocks, coastal cliff ledges, soil banks, and peatlands in the low Arctic and subarctic zones, tolerating periodic inundation, salt spray exposure, and freeze-thaw cycles that characterize coastal high-latitude environments. Like other mosses, it lacks true vascular tissue and absorbs water and nutrients directly through leaf surfaces, making it sensitive to desiccation but resilient to temporary submersion. Arctic and subarctic mosses are ecologically critical components of tundra carbon cycling, accumulating organic matter in cold, wet conditions and contributing substantially to the global peat carbon pool. Sanionia orthothecioides is classified as Least Concern by the IUCN, being widely distributed across coastal Arctic regions and not currently threatened by any major population-level pressures.

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.
