The sponges are aquatic, sedentary, filter feeding Metazoa with a cellular grade of construction, without organs, mouth or nervous tissue, with a body permeated with pores, canals and chambers and involving a unidirectional water current through the body propelled by random beating of flagella occurring on a single layer of flagellated cells called choanocytes and feed on suspended organic particles. Skeleton - made up mainly of spicules of silica or calcite and spongin fibres laid down around the spicules or parts thereof so that the skeleton held together in a reticulum, a set of plumose fibres, or as dense tracts of spongin and spicules.- New Record of Freshwater Bryozoa from Arunachal Pradesh, India

The Bryozoa or ectoprocta are small benthic, sessile, aquatic invertebrates growing as colonies of connected zooids on submerged substrates, feed on suspended organic particles which they captured by the whorls of ciliated tentacles (lophophore). Globally about 94 bryozoan species are found in freshwater, consisting of 24 genera and 10 families (Massard & Geimer, 2008). Most of these species belongs to exclusively freshwater inhabiting class Phylactolaemata.- On the First Record of Two Species of Fresh Water Leech (Hirudinea) from Arunachal Pradesh

Lingula is the oldest living genus belongs to the phylum Brachiopoda commonly known as 'Lamp shell'. It is flourished from Cambrian times to the present (MacGINITIE and MacGINITIE, 1968) and come down to the ages with little changes. Among the 150 extant species family Lingulidae, it is considered to be the most primitive and has only 12 species (living) belong to 2 genera (Emig, 1997). Genus Lingula is distributed in Asia, Australia, Europe and Africa while the other genus Glottidia confined only in the continents of America.- Mangrove Associated Sipunculid (Sipuncula : Phascolosomatidae) and Echiurid (Echiura: Thalassematidae) from Odisha Coast, India

The Sipuncula and Echiura form important groups of intertidal invertebrate distinguished by their members dwelling in burrowed substrata. They are found in the temporarily exposed intertidal limits to the abyssal depths of vast seas and also certain tropical estuaries of the globe. Though they are typically of marine origin but a few apparently well adapted to the estuarine environment.- Diversity and Distribution of Sea-Anemones (Cnidaria : Actiniaria) in the Estuaries and Mangroves of Odisha, India

Actiniarians, popularly called as 'Sea-Anemones', belongs to the phylum Cnidaria form an important group of intertidal invertebrate distinguished by their habit, habitat and beautiful colouration. This group was not elaborately studied from India. However Annandale (1907 & 1915), Carlgren (1925 & 1949), Parulekar (1968 & 1990), Seshyia and Cuttress (1971), Misra (1975 & 1976) and Bairagi (1998, 2001) worked on this group and a total 40 species of sea anemones belongs to 33 genera and 17 families so far recorded from India.- On a Collection of Echinodermata from Karnataka Coast, India

The Karnataka State of India has a 270 km long coast line bordering Arabian Sea. The habitats are mainly sandy with scattered rocks and rocky islands. The echinoderm fauna of the coast is poorly known. There are several scattered reports of echinoderms from Karnataka (see Sastry, 2007). However, the report of Patil (1953) includes the marine fauna exclusively of Karnataka and only Temnopleurus sp. of echinoderms from Karwar coast of Karnataka.- Animal Diversity in the Mangrove Forest at Bichitrapur of Balasore District, Odisha, India-A Case Study

The present work forms the preliminary study of ecosystem of Bichitrapur in Balasore district, though it covers a small area. A total 56 species of estuarine animals are found in the locality. They are normally mangrove associate animals, found in and over mangrove plants as borers or non-borers. These animals are either harmful to mangrove plants or opportunists by depending on mangroves for shelter or feeding. The dominating group in this mangrove is found to be the Molluscs, comprising 8 species of borers of mangrove-wood and 19 species as opportunistic epi-fauna. Crustaceans are the second diverse group in this ecosystem, represented by 13 species of crabs, 6 species of boring Isopods and a single species of Amphipod. The other epifaunal components comprise a few species of Cnidaria, Polychaetea, Echinoderm and some fishes, which are found on 7 species of mangrove plants in this ecosystem. But they seem to be non-specific to any mangrove plant species. An in-depth study of these faunal components in ecological viewpoints may provide pathway towards conservation and management of the mangrove ecosystems.Keywords
