Cave habitats
Terrestrial habitats
Many different terrestrial species of organisms, in relation to characteristics of substrate and position of habitats in caves, inhabit caves. In cave entrances usually trogloxene and troglophile can be found on walls and rocks, between and under rocks and on the organic matter. In these parts of the caves many species of harvestmans, centipedes, grasshopper, springtails, woodlice and other groups can be found. These cave entrances are rich in organic matter and sometimes can be attractive to inhabitants of the deeper parts of the caves which comes there for hunting or feeding. In deeper parts of the caves troglobites are adapted to less amount of food, complete darkness and stabile temperature. Many species of cave coleopterans, pseudoscorpions, woodlices, spiders, springtails can be found in deeper parts.
Some of these animals live on the ground, between and under rocks where they feed on small parts of organic matter or they hunt their prey. Other species can be found exclusively on the walls, cave speleothemes, in the wall cracks where they feed on small organic particles which are brought by water or they knit nets and hunt prey. Places with large amounts of guano is special habitat in caves. Huge density of guanophile organisms which feeds on guano or fungi and bacteria that grows on guano can be found on such places. These places are specially interesting for many predators.
