An anchialine system is a landlocked body of water with a subterranean connection to the ocean. Depending on its formation, these systems can exist in one of two primary forms: pools or caves. The primary differentiating characteristics between pools and caves is the availability of light; cave systems are generally aphotic while pools are ...
Speleophriidae is a family of copepods, comprising seven genera. [1] All are restricted to anchialine caves, with the exception of Archimisophria, which is found in the hyperbenthos of the depths of the Atlantic Ocean. [2]
Cave-inhabiting animals are often categorized as troglobites (cave-limited species), troglophiles (species that can live their entire lives in caves, but also occur in other environments), trogloxenes (species that use caves, but cannot complete their life cycle fully in caves) and accidentals (animals not in one of the previous categories).
They are free-swimming crustaceans, typically living in low-oxygen, brackish waters of near-marine caves, and their distribution is linked to the ancient Tethys Sea. The feeding technique of X. tulumensis is unique among crustaceans, and its venom is a useful adaptation that to some extent compensates for being sightless in a nutrient-poor or ...
These cracks then gradually get larger and turn into caves. If a cave wears through a headland, an arch forms. Further erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast, the stack. Eventually, erosion will cause the stack to collapse, leaving a stump.
