ABSTRACT
The marine milieu has proven to be an unexploited reservoir of great assorted assortments of bioactivates (bioactive metabolites) from marine ora and fauna with immense potential for pharmaceutical/biotechnological and other applications (Saravanan, 2014). Biphasic life cycle systems are present in the marine invertebrate that includes a pelagic larval stage that is morphologically distinctive from the adult form. Their larvae naturally metamorphose into juveniles or adults concurrently with, or unswervingly following completion out of the water column, they will consequently colonize and structure the benthic communities. Generally, the common features of marine invertebrates consist of remodeling of tissue and discrimination to be underneath hormonal or transcriptional control and are interceded by disparity gene and protein expressions to the cell (Chia and Rice, 1978; Okazaki and Shizuri, 2000a; Snelgrove et al., 2001; Fuentes et al., 2002; Fusetani and Clare, 2006). Figure 14.1 represents the taxonomy of marine invertebrates.
