Kallana is the Malayalam language name of a suspected species of dwarf elephants allegedly found in South India. Kaani tribals dwelling in the rainforests of the Western Ghats ( Kerala, India) claim that there are two distinct varieties of elephants in the Peppara forest range, one the common Indian elephants (Elephas maximus indicus), and the other a dwarf variety which they call Kallana. The name Kallana comes from the words "Kallu", which means stones or boulders, and "aana", which means elephant. The tribals gave the creatures this name because they see the smaller elephant more often in the higher altitudes where the terrain is rocky. Some tribals also call the delicate creatures Thumbiana (thumbi means dragonfly) for the speed with which the pachyderms run through trees and rocks when disturbed.
