Habitat & Geographic Range

Common Sea Groundling

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

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.

Common Sea Groundling

<em>Scrobipalpa nitentella</em>, the common sea groundling, is a small moth in the family Gelechiidae, order Lepidoptera, found along the coastal regions of northwestern Europe, with records from Belgium, Denmark, Norway, and Sweden. This species is characteristically associated with coastal and estuarine habitats, particularly saltmarshes and sandy shores where its larval host plants grow. As a member of the diverse Gelechiidae family, <em>Scrobipalpa nitentella</em> typically completes its life cycle on specific coastal plant species, with larvae feeding on or mining leaves and stems. Adults are small, inconspicuous moths that are active primarily at dusk or night. The species is listed as Least Concern by the IUCN, suggesting it is not currently facing significant population pressures, though its reliance on coastal habitats makes it potentially vulnerable to sea-level rise and coastal habitat degradation. Biological traits for this species remain poorly documented in the scientific literature, including specific data on average lifespan, body size, weight, and the precise identity of all larval host plants across its geographic range.

Leatherback Sea Turtle

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