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.
