Typically found in various aerial, terrestrial, and aquatic environments.

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.

Colima Warbler

<em>Leiothlypis crissalis</em>, the Colima Warbler, is a wood warbler in the family Parulidae. This species is assessed as Least Concern on the IUCN Red List. It breeds primarily in the Chisos Mountains of southwestern Texas in the United States and adjacent areas of northeastern Mexico, where it inhabits oak, juniper, and pine-oak woodland at higher elevations. <em>Leiothlypis crissalis</em> is a migratory species that winters in Mexico. The genus <em>Leiothlypis</em> was separated from <em>Vermivora</em> following phylogenetic revisions in the early twenty-first century. Colima Warblers typically forage in shrub and tree understories, gleaning insects and other invertebrates from vegetation. Diet, population estimates, and biological measurements such as average length, weight, and lifespan are not specified in available records. No specific country occurrence records are listed in the available data for this species. Its Least Concern designation reflects that current population levels do not indicate an elevated extinction risk, though the species' restricted breeding range in a single mountain range makes it of conservation interest.

Leatherback Sea Turtle

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