Habitat & Geographic Range

Anchovy-Eater

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate grasslands and steppes, among 9 distinct biome types spanning the Indomalayan and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Denmark, Norway, and Sweden.

Anchovy-Eater

The largest predatory fish on Earth, great white sharks can reach 6 meters and 2,000 kg, inhabiting cool coastal and offshore waters in all major oceans. Apex predators employing ambush attacks from below, primarily on marine mammals, large fish, and seabirds. Despite their fearsome reputation, unprovoked attacks on humans are extremely rare. Vulnerable, with populations declining from finning, bycatch, and targeted fishing despite legal protections in many jurisdictions.

Chrysosphaerella longispina is a colonial chrysophyte alga in the genus Chrysosphaerella, notable for the long silica spines (longispina: Latin, long spine) that project from each cell in the colony. The genus is characterized by spherical or discoid colonies of photosynthetic cells that each secrete siliceous scales and elongated spine-like appendages, making Chrysosphaerella colonies distinctively bristled and visible under light microscopy. The long spines of C. longispina likely serve as anti-predation structures that make the colonies more difficult for zooplankton to ingest. C. longispina is found in cold, oligotrophic freshwater lakes, particularly in Scandinavia, where comprehensive chrysophyte surveys have documented its presence. Chrysosphaerella colonies contribute to freshwater primary production and the cycling of biogenic silica, which upon cell dissolution is deposited in lake sediments as microscopically identifiable remains. These silica structures are widely used by paleolimnologists to reconstruct past changes in lake water chemistry, thermal stratification, and climate. The conservation status of C. longispina has not been assessed by the IUCN; the species is listed as Not Evaluated.
