'', a zoo-geographical hypothesis proposed by him that suggests that the central Indian Satpura Range of hills acted as a bridge for the gradual migrations of Malayan fauna into the peninsula and the Western Ghats of India. He supported the theory on the basis of torrential fishes which had special suckers to hold onto rocks. Later research however pointed out that his examples made use of unrelated species showing common characters that were independently evolved, that is they were examples of convergent evolution. Hora was also among the Indian pioneers of fish and wildlife conservation and pointed out the effect of dams on the migrations of riverine fishes and noted the poor design of fish ladders in Indian dams.
