Habitat & Geographic Range

Coachwhip ray

Gewöhnliche Kornrade

Habitat

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

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Coachwhip ray

The coachwhip ray, Urogymnus granulatus, is a large elasmobranch in the family Urogymidae found across the Indo-Pacific region, ranging from the Red Sea and East Africa through South and Southeast Asia to northern Australia and the western Pacific islands. It inhabits shallow coastal waters including coral reef flats, sandy lagoons, seagrass beds, and estuarine habitats, where it forages for benthic invertebrates and small fishes buried in the substrate. The coachwhip ray is characterized by an oval disc and a long, whip-like tail with one or more venomous spines at its base, giving the species its common name. The disc reaches up to 1.4 meters in width, making it one of the larger members of its family. Urogymnus granulatus is ovoviviparous, giving birth to live young after internal development, and has low reproductive rates that make populations slow to recover from exploitation. The species is classified as Vulnerable by the IUCN due to significant declines caused by intensive coastal fisheries across its range, particularly in South and Southeast Asia where it is commonly caught as bycatch or targeted for its valuable meat, skin, and gill plates in local markets. Habitat degradation from coastal development and coral reef decline compounds the threat to wild populations.

Gewöhnliche Kornrade

<em>Agrostemma githago</em>, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.
