Asperococcus ensiformis is a tubular to flattened brown alga forming elongated, sac-like or sword-shaped thalli attached to rocky substrates. It inhabits intertidal and shallow subtidal rocky shores of the North Atlantic and Mediterranean coasts. This photosynthetic macroalga grows on rocks and larger algae in wave-exposed coastal zones.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
