Organisms processing larval stages lay minute eggs with a very little (microlecithal) or no yolk material. Significance of larval stages they help in the dispersal of species, the larval stages are useful in finding the homologies and affinity of various groups. and the feeding and reproductive nature or evolutionary trends may be understood.The following book represents a total numbers of 63 larval forms, their Systematic position, Size Distribution, Habitat, Morphological characters, Special behavior and dictate the figure for readers as they easily understood.
