Sponges are mostly marine, comprising of 4562 species (Thomas, 1998). Amongst these, only about 100 species belonging to the family Spongillidae are freshwater sponges and distributed all over the globe (Thomas, op. cit.). These sponges grow as tufts or irregular masses on stones, sticks, logs, shells and other solid objects lying in freshwater. Some of these freshwater sponges occur in brackishwater also as reported by Annandale (1907a) from West Bengal, India.References

Bryozoa or Ectoprocta are small benthic, sessile and aquatic invertebrates growing as colonies of connected zooids on submerged substrates. They feed on suspended organic particles which they captured by the whorls of ciliated tentacles (lophophore). Of the estimated 8000 extant species of bryozoans (Ryland, 2005), only a small number are found in freshwater habitats. Till now 94 bryozoan species are found in freshwater consisting of 24 genera and 10 families (Massard and Geimer, 2008). Most of these species belong to the exclusively freshwater inhabiting class Phylactolaemata and reproduce asexually by means of statoblasts (buoyant floatoblasts and fixed sessoblasts), which are very important in identification of species. Freshwater bryozoan colony adheres to the surface of any substratum inside the water bodies, i.e., aquatic weeds, logs, stones, bricks or any other artificial substratum in the ponds, lakes, water reservoirs, streams, and rivers.References

Although mangrove flora of Orissa are well inventorised, fauna inhabiting mangroves of this state, especially the lower invertebrates are very poorly known, barring a single publication by Chadha and Kar (1999). During the faunistic survey in March, 2011 under the project, "Mangrove Associated fauna of Orissa coast" the authors had observed and collected three species of invertebrates, namely, Pleurobranchia globosa (Phylum Ctenophora), Anelassorhynchus microrhynchus (Phylum Echiura) and Phascolosoma arcuatum (Phylum Sipuncula) from mangrove habitats of Orissa. Among these, P. globosa was observed to be very common in the fishing nets at Hukitola (River Mahanadi) and Bandar (River Devi) while A. microrhynchus and P. arcuatum were collected from Bandar (Devi River, district Jagatsingpur and Balabhadrapur in district Puri) and Jashipur (Budha Balanga River, district Balasore). P. arcuatum was found in the muddy bank in sparsely distributed mangroves. P. globosa was observed in Mahanadi estuary surrounded by dense mangroves while A. microrhynchus had been collected from dense (in Bandar) as well as sparse (in Balabhadrapur) mangroves. A perusal of literature reveals that the sipunculid P. arcuatum had been reported earlier from mangroves of Andaman Islands (Das and Dev Roy, 1989) and all the three species from Sundarbans mangrove region (Mandal and Nandi, 1989).- Freshwater Sponges of Arunachal Pradesh, India

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 Karnataka state on west coast of India abutting the Arabian Sea has a long and narrow coast with small crescent shaped pocket beaches. It is interspersed with rocky head lands, spectacular spits, estuaries, shallow lagoons, mudflats and a few patches of mangroves. The northern coast is rocky while the southern coast has long sandy beaches.- 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
