Weißkopf-Seeadler

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.

Nodularia litorea is a filamentous, nitrogen-fixing cyanobacterium found in coastal and estuarine environments, tolerating a range of salinities from brackish to marine conditions. It forms short trichomes with alternating vegetative cells and heterocysts. Like other Nodularia species, it may produce hepatotoxins (nodularin) under bloom-forming conditions, posing risks to aquatic life and water quality.
