Habitat & Geographic Range

Klappenassel

Habitat

Typically found in marine, freshwater, and terrestrial environments.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Wolf

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Klappenassel

The Clawfooted Marine Isopod belongs to the crustacean order Isopoda, a diverse group of aquatic and terrestrial arthropods with flattened, segmented bodies and seven pairs of walking legs. Marine isopods occupy a vast range of habitats from intertidal zones to hadal trenches, and many species are adapted to specific substrates, host organisms, or depth ranges. Species commonly referred to as clawfooted isopods often belong to families such as Gnathiidae, Cirolanidae, or Aegidae, characterized by robust, claw-tipped pereopods used for grasping substrate or hosts. Many marine isopods are scavengers or detritivores, consuming decomposing organic matter on the seafloor, while others are parasitic on fishes or invertebrates. The segmented exoskeleton is periodically molted as the animal grows. Marine isopods are important components of benthic food webs, serving as prey for fishes, crabs, and other invertebrates, while also contributing to the decomposition of organic matter. Specific information on the Clawfooted Marine Isopod's distribution, ecology, and conservation status depends on the exact species referred to, as the common name may apply to more than one species within this large and taxonomically complex order.

Wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.
