Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

ciliated sponge

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Denmark, Norway, Portugal, and Sweden.

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.

ciliated sponge

Sycon ciliatum, the ciliated sponge, is a small calcareous sponge in the family Sycettidae, widely distributed along the coasts of Europe and the North Atlantic. It grows as a slender, vase-shaped or cylindrical solitary body, typically 1–5 centimeters tall, with a distinctive fringe of long spicules surrounding the apical opening (osculum), which gives it its ciliated appearance. The sponge is white to pale yellow and is found attached to rocky substrates, algae, seagrass, shells, and pier pilings in shallow subtidal and lower intertidal zones. Sycon ciliatum is a filter feeder, drawing water through its porous body wall and extracting bacteria, phytoplankton, and organic particles. It is one of the most studied calcareous sponges and has been used extensively in developmental biology research due to its relatively simple body plan. The species is not assessed by the IUCN. Calcareous sponges in the class Calcarea, including Sycon, have been important in understanding the evolution of sponge body plans. Sycon ciliatum reproduces both sexually, releasing larvae that settle on available substrates, and asexually by budding. It is common and not considered threatened across its European coastal range. The species provides microhabitat for small invertebrates and forms part of the diverse encrusting community of rocky subtidal habitats.
