Anisonema multicostatum is a heterotrophic euglenozoan flagellate found in freshwater and soil environments. Like other members of the genus Anisonema, it feeds by phagocytosis of bacteria and organic particles.

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.
