The earlier workers thought that the interstitial animals of marine beach sand have a limited range of distribution due to their restricted habitat, feeble powers of locomotion, thigmotactic activity and lack of pelagic larval stages in development. But, the taxonomic researches conducted recently in widely separated parts of the world. have shown a remarkable degree of identity of the species reported from different continents. It is interesting to note that the same species could occur in different geographical regions well isolated by the oceans. It is probable that the presentday interstitial fauna is actually a relic of the by-gone ages, before the continents have separated. In the present article, the geographical distribution of certain widely distributed interstitial species is discussed by the author in the light of the above concept.
