Cave habitats

Cave habitats can be divided by several factors, but all of them have some common features:

lack of light, with the exception of cave entrances
relatively small amount of food, which all comes from outside of the caves
relative humidity is very high and stabile, and depends on air flow and circulation in caves
relatively stable air temperature which usually mach annual average temperature of the cave area, but also depends on the morphology, hidrology and proportions of the cave
relatively low and stabile temperature of water

Cave habitats can be divided in terrestrial, transitional and aquatic habitats.
