Range

Found in Portugal. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Click beetle

Click Beetle 3 is a third entry for species sharing the common name click beetle within the diverse family Elateridae, reflecting the family's enormous species richness across global ecosystems. Click beetles exhibit considerable morphological variation, from drab, cryptically colored species common on bark and in soil to brilliantly metallic or spotted species found in tropical forest canopies. The click mechanism, unique to the family Elateridae and a few related families, involves a prosternal process that fits into a mesosternal cavity. When the beetle is inverted, muscular tension builds until the spine snaps into the cavity with an audible pop, launching the beetle upward. Adults are generally poor fliers but use this jumping ability effectively to escape predators and right themselves. The larval stage is typically the longest phase of the life cycle, often lasting two to five years, during which wireworms inhabit soil or decaying wood. Some click beetle species require old-growth forest conditions for successful reproduction and are used as indicator species for forest conservation assessments. The precise ecology, host associations, and conservation status of this entry depend on the specific species referenced.

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.
