Functional morphology is an effective approach to understand and compare taxonomic units with different phenotypic characteristics. To delineate the functional traits with a view to determine the discrimination level and degree of functional niche overlap. Significant differences are observed in the functional traits between species providing a low functional niche overlap. We support the hypothesis that in resource poor environments species coexisting due to high resource partitioning or different strategies for use of these resources. This is a first attempt to compare the morpho-functional characteristics and niche partitioning in the deep-sea fish assemblages from the Indian waters.
