Range

Found in Portugal. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Leatherback Sea Turtle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 5 distinct biome types spanning the Australasia and Indomalayan and Neotropic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Costa Rica, Indonesia, Malaysia, and Trinidad and Tobago. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cigarette Beetle

Sphaericus velhocabrali is a beetle in the family Colydiidae (or allied family), endemic to Portugal and classified as Critically Endangered by the IUCN. This species is known from extremely limited localities in the Iberian Peninsula and represents one of the most threatened coleopteran taxa in Europe. The genus Sphaericus comprises small, cylindrical bark beetles associated with decaying wood and fungal substrates in old-growth forests. Sphaericus velhocabrali likely inhabits ancient forest remnants in Portugal, where it is associated with dead and decaying timber of native hardwood trees. Its Critically Endangered status reflects an extremely small known range, very few known populations, and ongoing habitat loss from logging, land conversion, and the replacement of native forest with eucalyptus and pine plantations across much of Portugal. Veteran and ancient trees that provide suitable dead wood habitat have become rare in the intensively managed Portuguese landscape. Little is known about the detailed ecology, biology, or reproductive habits of this species, and population estimates are unavailable. Conservation action for this beetle depends on the protection of old-growth forest remnants and the promotion of veteran tree retention in Portuguese forests. Its discovery and description are relatively recent, highlighting the ongoing documentation of European invertebrate biodiversity.

Leatherback Sea Turtle

The leatherback is the largest living turtle and the fourth-heaviest reptile. Unlike other turtles, it has a soft, leathery shell.
