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).

Common Spiny Lobster

Habitat

Typically found in marine, freshwater, and terrestrial environments.

Range

Found across Europe (8 countries).

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.

Common Spiny Lobster

<em>Palinurus elephas</em>, commonly known as the common spiny lobster, is a large marine crustacean in the family Palinuridae, distributed across the northeastern Atlantic Ocean and Mediterranean Sea. This species typically inhabits rocky and biogenic reef habitats at depths ranging from the shallow subtidal zone to approximately 200 metres, where crevices and caves provide shelter during the day. Its geographic range extends from the British Isles and the Azores southward along the Atlantic coasts of Europe and North Africa, and throughout the Mediterranean. The species has not been formally evaluated under IUCN Red List criteria, though commercial populations have declined significantly across much of its range due to intensive fishing pressure. <em>Palinurus elephas</em> lacks the large claws characteristic of true lobsters, relying instead on long, spiny antennae for defence and sensory purposes. It is omnivorous, typically feeding on molluscs, echinoderms, algae, and organic detritus on the seafloor. The species can reach a total body length of approximately 50 cm and may weigh up to approximately 4 kg in large individuals, though average lifespan measurements remain poorly documented. Spawning occurs in summer, with females carrying egg masses under the abdomen. Commercial fisheries management increasingly focuses on minimum landing sizes and seasonal closures.
