American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Kariarchaeum pelagius is a member of the DPANN archaea group, representing ultra-small, genomically streamlined organisms found in pelagic marine environments. Like other DPANN archaea, it likely relies on metabolic partnerships with other microorganisms due to its reduced biosynthetic capabilities. Its discovery in open ocean waters extended knowledge of DPANN archaeal diversity beyond sediment and acidic environments.
