Habitat & Geographic Range

Cloudy cat shark

Habitat

Typically found in marine environments from coastal waters to deep ocean.

Common corncockle

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.

Cloudy cat shark

Cloudy catsharks are small, benthic sharks in the family Scyliorhinidae known for their mottled, cloudy patterning of dark brown or grey patches and spots on a lighter background, providing camouflage against rocky reef and sandy seafloor substrates. Members of this group inhabit shallow to moderate-depth coastal and shelf waters across Indo-Pacific and Atlantic regions, living primarily as nocturnal predators of bottom-dwelling fish, cephalopods, and crustaceans. Catsharks are oviparous, depositing elongated, ridged egg cases often called mermaid's purses attached to coral, algae, or rocky substrate, from which juveniles emerge after weeks to months of development. Several Scyliorhinus species are locally common in their ranges, while others with restricted distributions face pressure from bycatch in commercial fisheries targeting shrimp and demersal fish with bottom trawls, gillnets, and longlines. Catsharks serve as important components of reef and shelf ecosystem food webs as both predators and prey of larger sharks and marine mammals. Most catshark species occupy relatively shallow, accessible habitats where human fishing pressure is greatest.

Common corncockle

<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.
