There are 34 MPAs in India comprising of 6272 sq.km of area. Compared to the size of coast, contribution of MPAs in India is only about 4% and these are not distributed evenly; most of them being on the east coast (30). West coast of India has only 4 MPAs (SCBD, 2006). Coastal Konkan in the state of Maharashtra has only one protected area. With an aim to identify potential MPAs, authors made comprehensive studies on coastal Konkan with an aim to identify the ecologically and biologically significant areas (EBSAs). The studies showed the rich diversity of rocky and sandy shores, corals, mudflats, luxuriant growth of mangroves and sea grass beds clearly indicating the presence of higher grade sustained ecological functioning. On this background, a report has been published during the Convention on Biodi...

of India. This species has broadly rounded anterior end, tapering body, distinct orange-yellow, black and white frontal transverse
bands and yellow-black longitudinal stripe. For the first time histological details of this species are presented. This confirms
the presence of a pair of free prostatic vesicles and sclerotized stylet peculiar to the genus Prosthiostomum. This species is
known from Japan, Micronesia, Papua New Guinea, the Red Sea and Singapore. This is also a new record of the family Prosthiostomidae from this coast. To consider the currently known two colour morphs of this species, other than presented here, a comparative examination of the reproductive system and molecular details is needed.

These belong to family Discodorididae with diversity of around 250 species worldwide. Being nudibranch, these molluscs have lost shell and no remnants are found in contrast to other shelled associates. So identification is based on the external and internal morphology. Majority of the records are from east coast of India and the records from west coast are scanty. A total of 33 species have been recorded from India till now. The morphological characters were used for taxonomy of discodorids. This study is an attempt to present diversity of discodorid sea slugs recorded during 2011-2014 along the intertidal areas of Maharashtra and Gujarat. Surveys were conducted fortnightly along the few sites of Gujarat like Dwarka, Poshitra, Narara and of Maharashtra like Bhatkarwada and Mirya. A total of 10 genera and 14 species of the discodorids were recorded, in which Sclerodoris apiculata was first time recorded from Gujarat; a species Atagema tristis was rediscovered after its last report in 1952 and two species namely Rostanga cf. arbutus and Thordisa sanguinea are new records for India.

It is the third known record of this species from India, observed after a long gap of 60 years. The last known record of this species from India was by Satyamurti (1952), from the Gulf of Mannar on the south-east coast. Specimens were collected in the intertidal rocky shores of Maharashtra and Gujarat. The occurrence of the species at three study sites confirms its range in this part of the Indian coastline.

India is bracing for large coastal infrastructure development, which will impact intertidal biodiversity and the Maharashtra coast is not an exception. It is therefore essential to develop baseline information on inter-tidal marine biodiversity. As part of this effort, scientists are working on various taxa, and opisthobranchs are one such group under study. They are beautifully colored with highly diverse adaptations to compensate for the loss of shell during the course of evolution. Opisthobranchs are poorly studied from Indian coasts, and recent work on opisthobranchs was carried out by Apte (2009), Apte et al. (2010), Apte & Salahuddin (2011), Bhave & Apte (2010) and Ramakrishna et al. (2010). The present paper deals with a record of the goniodorid nudibranch Okenia pellucida Burn, 1967. There are very few records of goniodorids from India (Alder & Hancock 1864; Winckworth 1946; Ramakrishna et al. 2010). Table 1 provides the checklist of goniodorid species hereto recorded from the Indian coasts.

The coast is known to host a high diversity of marine habitats, and flora and fauna. Opisthobranchs have received attention only recently, Maharashtra coast being the least explored. The paper presents 16 species of opisthobranch of which 15 are new records to Maharashtra and 8 to India.

Historical studies are centred mostly on known species rich localities and are not evenly distributed along all coastal states. Opisthobranchs are among the least studied group of molluscs in India and the work carried out on the opisthobranch fauna is scanty and sparse. Though India has over 8000 km long coastline along nine coastal states and two oceanic archipelagos and have diverse habitats such as coral reefs, sandy shores, rocky patches, mangroves as well as large mud flats; yet records of Indian opisthobranchs are very less. This study revealed that 311 species are known from India distributed over 7 orders, 53 families and 141 genera.

On this background, a report has been published during the Convention on Biodiversity (CBD) COP11 on diversity of coastal ecosystems of Konkan. Through this initiative we aim to assist state and federal government in formulating participatory conservation strategies towards meeting Government of India’s obligations under CBD. One of the sites recommended in the study has now been identified as a potential EBSA under Ministry of Environment and Forest (MoEF) Government of India and GIZ, German Federal Ministry for the Environment under Indo-German Biodiversity Programme.
