Habitat & Geographic Range
Canadian beaver
Typically found in grasslands, forests, and vegetated habitats.
Widely distributed across Europe (15 countries), North America (United States), and South America (Argentina, Chile).
Comet Darner
Typically found in virtually all terrestrial and freshwater habitats.
Found in United States.
Canadian beaver
The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.
Comet Darner
<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.
