Habitat & Geographic Range

Clubnose guitarfish

gray wolf

Habitat

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

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Clubnose guitarfish

Glaucostegus thouin, the clubnose guitarfish, is a large elasmobranch in the family Rhinobatidae native to the Indo-Pacific Ocean, ranging from the Red Sea and East African coast across the Indian Ocean to Southeast Asia and northern Australia. This ray reaches lengths of up to approximately 2.7 m and has the characteristic flattened body with a pronounced snout and pectoral fins that give the family its guitarfish name. Like other guitarfishes, it inhabits shallow coastal waters, estuaries, and sandy or muddy seabeds where it forages for benthic invertebrates and small fish. The clubnose guitarfish is listed as Critically Endangered by the IUCN due to severe population declines driven primarily by overfishing and bycatch in coastal fisheries across its range. Shallow-water elasmobranch species are particularly vulnerable to depletion because they are easily caught in inshore nets and have slow reproductive rates. The species has been assessed as having suffered extremely high population declines over recent decades, with significant range contractions documented across much of its former distribution. Effective fisheries management and marine protected areas in its core habitat are critical for its recovery.

gray wolf

O lobo-cinzento (Canis lupus), o canídeo selvagem mais amplamente distribuído, ocorre da América do Norte à Eurásia em habitats diversos, incluindo tundra, florestas e pradarias. São animais altamente sociais que vivem em matilhas familiares lideradas por um casal reprodutor dominante. Como predadores-chave, os lobos regulam as populações de presas e moldam profundamente a estrutura do ecossistema, como demonstrou sua reintrodução em Yellowstone. Antes muito perseguidos, as populações estão se recuperando em muitas regiões.
