Habitat & Geographic Range

Common Seal

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Found across Europe (7 countries) and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Common Toad Rush

Habitat

Found across multiple habitat types including tropical and subtropical grasslands and savannas, flooded grasslands and savannas, and deserts and xeric shrublands, among 4 distinct biome types spanning the Afrotropic and Neotropic realms.

Range

Widely distributed across Africa (Namibia, South Africa), Asia (Taiwan), Europe (8 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (4 countries).

Common Seal

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.

Common Toad Rush

<em>Juncus bufonius</em>, commonly called toad rush, is a small annual rush in the family Juncaceae with a near-cosmopolitan distribution, occurring on every continent except Antarctica. It is found throughout Europe, Asia, Africa, the Americas, and Australia, thriving in a wide diversity of habitats including muddy pond margins, seasonal wetlands, trampled pathways, agricultural fields, and disturbed moist ground. The species typically grows in low-lying areas that experience seasonal flooding or waterlogging, tolerating a range of soil types from sandy to clay-rich. <em>Juncus bufonius</em> is a diminutive plant, typically reaching 5 to 35 centimeters in height, with slender, wiry stems and inconspicuous greenish flowers arranged in loose, branched inflorescences. As an annual, it completes its life cycle rapidly, producing abundant small seeds that persist in the soil seed bank and facilitate colonization of newly disturbed wet habitats. The species plays an ecological role as an early colonizer of open, moist ground and provides microhabitat and food resources for small invertebrates. It is currently assessed as Least Concern by the IUCN, with a stable and widespread global population. Biological traits such as average lifespan duration beyond a single season, body length measurements, and weight remain poorly documented in the scientific literature.
