Description Taxonomical awareness on species, the intraspecific and interspecific relations etc, are the
necessary pre requisites in different fields of applied biology, such as in biological resources
management and conservation, in mariculture ventures, in pest/pathogen control and identification,
etc. Generally, there are two contexts in which significant problems arise in species identification,
where the molecular approaches are applicable. The first concerns the very fundamentals of
taxonomy, in identifying the species, the phylogenetic status and the identification at subspecies
and hybrids level. The second concerns to ecologists are the issue of identifying the species sex, or
identity of individuals under circumstances where simple morphology cannot be relied upon.
Biodiversity studies require species level analyses to assess the community structures. In conventional
taxonomic practice, organisms were classified based on their fine morphological characters,
comparative osteology, etc., which are more time consuming, laborious and expensive. Moreover,
in some situations, morphological variation arises due to the environmental factors rather than genetic
causes and is therefore not heritable. In this context, classification of organisms based on the
molecular variations using the modern molecular tools has got a wide acceptance globally.
