Cave research, encompassing the study of speleology and biospeleology, is still in its infancy in India. Although there are thousands of caves in India, research expeditions occur in few states. The Siju Cave of state Meghalaya is the first limelighted natural cave from India. Several studies were carried out in this cave in the early 20th century. The Kotumsar Cave of Central India is one of the most explored caves of India, and biologists have classified many types of cavernicoles, i.e. trogloxenes, troglophiles and troglobites, from this cave. The Indian institution mainly engaged in this particular field of research and conversational issues of Indian caves is the Raipur-based National Cave Research and Protection Organisation (founded and headed by Dr Jayant Biswas). The other notable organisation is Meghalaya Adventurer Association (founded and managed by Brian Dermot Kharpran Daly) which mainly involved in the caving and cave explorations of the existing caves of the state Meghalaya.
