Habitat & Geographic Range
Cluster Spiderhead
Typically found in diverse terrestrial habitats from tropical forests to temperate regions.
Epaulard
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).
Cluster Spiderhead
Serruria glomerata, the cluster spiderhead, is a flowering shrub endemic to the Cape Floristic Region of South Africa, one of the world's six recognized floral kingdoms and a global biodiversity hotspot. The species belongs to the family Proteaceae and is restricted to fynbos, the fire-adapted shrubland of the Western Cape characterized by nutrient-poor, often acidic soils of sandstone or granite origin. Like other Serruria species, S. glomerata produces intricate, lace-like flower heads composed of many small flowers surrounded by feathery, spider-like bracts, which are pollinated by a range of insects including bees and beetles. Serruria glomerata is assessed as Least Concern by the IUCN, though like all Cape fynbos plants it exists within a biodiversity-rich but geographically confined region under persistent pressure from agricultural expansion, urban development, invasive alien plants, and altered fire regimes. The genus Serruria comprises around 55 species, most endemic to the Western Cape. Many require fire for seed release and germination, and some have obligate relationships with specific ant species that cache and bury their seeds, a process called myrmecochory that aids in seed dispersal and protection from fire.
Epaulard
The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
