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.

Common Crabgrass

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Africa (8 countries), Asia (8 countries), Europe (18 countries), North America (10 countries), Oceania and the Pacific (12 countries), and South America (5 countries).

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.

Common Crabgrass

<em>Digitaria ciliaris</em>, commonly known as common crabgrass or southern crabgrass, is an annual grass in the family Poaceae. It has a near-cosmopolitan distribution, occurring across tropical, subtropical, and warm temperate regions on multiple continents. This species typically colonizes disturbed habitats including lawns, gardens, roadsides, cultivated fields, and waste ground, making it one of the most widespread grass weeds in the world. Common crabgrass spreads rapidly via its sprawling, branching stems that root at the nodes when they contact moist soil. It produces slender, finger-like racemes bearing small, paired spikelets. The species thrives in warm weather and full sun, declining with the onset of cooler autumn temperatures. While it is considered a troublesome weed in many agricultural and horticultural contexts, it also provides ground cover and food for various seed-eating birds. Biological traits of this species remain poorly documented in the scientific literature.
