Abstract: Marine environment comprises complex ecosystems and many of the organisms are known to possess bioactive components as a common means of self-defense or for the protection of eggs and embryos. In recent years, many bioactive compounds have been extracted, characterized and purified from various marine animals like bacteria, algae, dinoflagellates, tunicates, sponges, soft corals, bryozoans, cephalopods, and echinoderms. Present review consists of the research work done on the biology of the cephalopods, mainly pertaining to the feeding strategies (the salivary gland toxins, body and liver oils), the reproductive strategies (the ovarian-peptides, the nidamental gland products, accessory nidamental gland products and the associated symbiotic bacteria), and the defence mechanisms (the ink glands and their bioactive products, the squid-vibrio association, the camouflage colouration mechanisms and the reflectin-proteins). The learning capabilities and personalities of octopods have been a matter of great interest in cephalopod ethology. The aspect of cephalopod welfare in laboratory and field studies merits scientific debate because of the biological and behavioural complexities exhibited by these highly evolved, lovable invertebrates.
