Recent collections from the western and southern coasts of India recorded two species of Stylissa Hallmann (Scopalinida, Scopalinidae). Stylissa soestii sp. nov. was collected from St. George Island in Goa, Hare Island in the Gulf of Mannar and the Palk Bay. It has six distinct different morphologies and sizes of styles, in addition to the typical gently curved stout and thin styles characteristic of Stylissa, and two different morphologies of strongyloxeas and rare strongyles. Stylissa carteri (Dendy, 1889) was reported previously from India (Gulf of Mannar and Pearl Banks of Tuticorin) and is redescribed here from populations in Palk Bay, east coast of India, in addition to Muttom, Vizhinjam and Lakshadweep islands, which are the first records of S. carteri from the west coast of India.

ABSTRACT A survey of the distribution, percentage coverage, and diversity of octocoral fauna on the south-west coast of India yielded fourteen species from six families: Clavulariidae, Nephtheidae, Melithaeidae, Plexauridae, Gorgoniidae and Ellisellidae. This study produced ten new zoogeographical records of octocoral species to India, two species which were first records to the shallow water fauna (11–12 m depth), and one found to be a potential new record to the Indian coast. Octocoral coverage was <1% at all sites and diversity ranged from 6–13 species among the five study sites.

Mortality from the tsunamis was high, with more than 7,000 deaths in the Nicobar group alone (the final number may never be known as many indigenous people on remote islands may have perished). On the mainland, there were a similar number of fatalities; The greatest losses were in fishing communities although the waves destroyed roads, jetties, other basic infrastructure and entire villages; There was major damage to the coastal resources of southeast India, particularly to mangrove and coastal forests. On the Andaman and ...

An inventory of sponges from the shallow subtidal reefs of the west and east coasts of southern India is presented. The specimens offered in this paper were based on in-situ collections unlike the previous records of dry and net-entangled collections. A total of 101 species belonging to 12 orders, 22 families, 5 subfamilies and 44 genera from 4 subclasses of Class Demospongiae and one species from Class Calcarea are recorded. We recorded 18 new records to India, six new species combinations, 37 potential new records, and 40 species for the first time from the southwest coast.

Coral reefs were surveyed at three islands (Kavaratti, Kadmat and Agatti) of Lakshadweep during February 2005 using the Line Intercept Transect method. The percent coverage of coral in all the three islands was good (55%), dominated by Acropora spp. (33 %) of the live coral cover. Twenty three genera of corals are reported with two new records for the Lakshadweep islands. No apparent bleaching and crown-of-thorns starfish (COTS) related mortality of coral was observed in the three islands. The abundance and distribution of corals and associated biota were recorded along with the characterization of the benthic communities at these sites.

An undescribed species of fish (Eviota sp.) is the first report from a sponge and a critical finding where the coral reef-associated biodiversity remains insufficiently explored especially in the Great Barrier Reef, Australia. This report showed that fishes are species-specific in choosing their host. This finding is also expected to lead to further investigations on Eviota sp. and other fish associated with sponges.

During an examination of xeniid octocorals held in the collections of the California Academy of Sciences (CAS) it was determined that identification to the species level was severely limited by the incomplete data present in most species descriptions published prior to 1950. A lack of consistent use of morphological characteristics by authors was found to be the most common difficulty, followed by limited or non-existent in situ data of the species being described. Descriptions from the later part of the twentieth century offered a more complete and detailed account of species. This paper presents the status of the Xeniidae by reviewing its two hundred year taxonomic history, examines the worldwide distribution of xeniids to date, and identifies the current challenges in xeniid systematics. It provides an overview of trends in modern taxonomy including in situ data collection, molecular analysis, and scanning electron microscopy. This last technique illustrates the micro-structural ...

Fourteen species of amphipod are recorded as endocommensal with the sponges Coelocarteria singaporensis, Coscinoderma mathewsi and Ircinia microconulosa on the Great Barrier Reef. The genus Leucothoe is represented by three new species, one specific to each of the three sponges. Hyperadult males of Aoroides parvus Myers are also described.

This study reports the occurrence of the parasitic isopod, Norileca indica, below the intestinal tract of Indian mackerel, Rastrelliger kanagurta for the first time from Goa, India. These parasites cause adverse environmental health and food safety concerns calling for close monitoring of food fishes.

It provides an overview of trends in modern taxonomy including in situ data collection, molecular analysis, and scanning electron microscopy. This last technique illustrates the micro-structural features of the sclerites or skeletal elements, a major taxonomic character of octocorals including the Xeniidae. The modern taxonomic methods outlined here are applicable for both xeniids and octocorals in general.
