Anchialine caves contain haline bodies of water with underground connections to the ocean
and limited exposure to open air. Despite being found on islands and peninsular coastlines …

Opsins are transmembrane proteins that have a covalent bond with a chromophore 11-cis-

This study asked whether reductive traits in cave organisms evolve at a slower pace
(suggesting neutral evolution under relaxed selection) than constructive changes, which are …

Background The underlying mechanisms and processes that prompt the colonisation of
extreme environments, such as caves, constitute major research themes of evolutionary …

Animals that inhabit subterranean environments often undergo various distinct phenotypic
modifications (referred to as “troglomorphy”) as they transition to life in perpetual darkness …

It is a matter of common information that a number of our streams and rivulets harbour small
animals, rarely more than three or four inches long, which are very similar to little lobsters …

Copidaster cavernicola n. sp. is described from an anchialine cave system in Cozumel,
Mexico. Copidaster cavernicola differs from its congeners in having 1–8 papulae in each …

Crustaceans are associated with a wide diversity of hosts, using both chemical and visual
cues to recognize them. The pea crab Dissodactylus primitivus is an ectoparasite of two …
