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.

Rhizocarpon richardii is a crustose lichen that forms tightly adhered patches on siliceous rocks, typically displaying a pale greenish-grey to yellowish thallus divided by a dark prothallus. It inhabits exposed rocky outcrops, cliff faces, and boulders in montane and alpine zones across Europe and beyond. This saxicolous species is highly sensitive to atmospheric pollution.
