Rhodoliths are the prominent global reef builders, providing a hard calcium carbonate substrate to develop coral polyps and several marine algae. Studies on rhodoliths in the Gulf of Mannar Biosphere Reserve are very scarce. The present study investigated the various forms of crustose coralline algae inhabiting coral reefs in three islands of the Gulf of Mannar Biosphere Reserve. Eleven coralline algal genera with various morphological forms such as encrusting, fruticose, layered, lumpy, and warty were recorded. Further, the study infers that molecular assessment of the biodiversity of these rhodoliths is required to discriminate morphological similarities and confirm the species identity.

The application of marine plants such as seagrasses, seaweeds and mangroves for the production of perfumes are relatively less familiar to perfume industry. In the present study, a red seaweed Portieria hornemannii showing strong fragrance, collected from coral reefs of Gulf of Mannar, southeast coast of Tamil Nadu, India is proposed as a potential source of fragrance for perfumes. This species has a distinctive essence of perfume like flowery scents and can give off pleasant fragrance immediately after rubbing or rupture. Gas Chromatography and Mass Spectrometry analysis of methanol extracts of P. Hornemannii revealed the presence of chemical components N'-(3-Phenyl-2-Propenylidene)-2-(4-Chlorophenoxy) acethydrazide and 4, 5-Dichlorotricyclo [4.4.0.0(2,8)] dec-3-ene.

A massive Scyphozoan jellyfish bloom has been encountered in branching coral, Acropora dominated reef area in the southern part of Hare Island of Gulf of Mannar region, Tamil Nadu. The live specimens were identified as Pelagia noctiluca (Forskal, 1775), adding a new occurrence record to the Gulf of Mannar biodiversity. A sudden outburst of P. noctiluca bloom represented thousands of live specimens (> 100/m(2) approximately) in the south side of Hare Island.

Mass mortality of sea urchin, Salmacis virgulata scattered over the periphery of Dhanushkodi beach, was observed on February 13, 2019. More than 100 numbers of recently dead and dying specimens were found within a 10 m(2) area on the sandy beach. Beach profiles indicated several hundreds of exoskeletons of previously dead S. virgulata were washed ashore and buried in sand and withering seagrass. The causative agent responsible for mass mortality of S. virgulata is yet to be discovered. However, observations on wave approach toward shore indicated possible evidence that it could be due to a combination of strong nearshore waves and currents. This observation raises a critical research concern to investigate etiology of S. virgulata for species conservation.
