The scientific study of living organisms in caves is known as biospeleology.
Furthermore, the idea that genuinely hypogeal organisms are the product of a long process of adaptation has been put in doubt by recent research on volcanic islands, another setting long ignored by traditional biospeleology. Thus, for example, the island of Hierro, the youngest of the Canary Islands, with an estimated age of 800,000 years, has lava tubes with a fauna rich in troglobionts, of which the most interesting is without doubt the heteropteran Collartida anophthalma, whose greatly modified morphology is an adaptation to life in caves.
