A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes). [1]
Troglophiles: species living mainly aboveground but also in subterranean habitats. These are further divided into eutroglophiles (aboveground species also able to maintain a permanent subterranean population) and subtroglophiles (species inclined to perpetually or temporarily inhabit a subterranean habitat, but strongly associated with ...
These are the true cavernicole species; troglobites rather than troglophiles or trogloxenes. These include; spiders and insects. Cavernicolous insect species rarely are adapted to move from cave to cave, so each species or community generally will be restricted wholly to certain caves or cave systems each, and commonly will have evolved in ...
troglophiles: species living both in subterranean and in epigean habitats. Troglophiles are also divided in eutroglophiles (epigean species able to maintain a permanent subterranean population) and subtroglophiles (species inclined to perpetually or temporarily inhabit a subterranean habitat, but intimately associated with epigean habitats for ...
Troglomorphism is the morphological adaptation of an animal to living in the constant darkness of caves, characterised by features such as loss of pigment, reduced eyesight or blindness, and frequently with attenuated bodies or appendages.
Troglophiles can live part or all of their lives in caves, but can also complete a life cycle in appropriate environments on the surface. Examples include cave crickets , bats , millipedes , pseudoscorpions and spiders.
Map of North America. This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
This is a list of North American mammals. It includes all mammals currently found in the United States, St. Pierre and Miquelon, Canada, Greenland, Bermuda, Mexico, Central America, and the Caribbean region, whether resident or as migrants. This article does not include species found only in captivity.
