Anabaena is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets. Production…

Blue Green Algae
Scytonema is a genus of photosynthetic cyanobacteria that contains over 100 species. It grows in filaments that form dark mats. Many species are aquatic and are either free-floating or grow attached to a submerged substrate, while others species grow on terrestrial rocks, wood, soil, or plants. Scytonema is a nitrogen fixer, and can provide fixed…

Blue Green algae
loeothece Valve slightly sigmoid, linear-lanceolate, with subacute ends, 55-85 µm long, 8.5-12.5 µm wide. Raphe sternum with single curvature, raphe angle +4 to +8°, practically median throughout. Central raphe fissures oppositely deflected dimorphic crooks, difficult to see in LM. Terminal areas very small triangles in semilateral position. A small apical microforamina segment is present at…
Green Algae
Coelastrum Thalli forming 4, 8, 16, 32 or 64 (-128) celled coenobia to ca. 100 &m diameter, organized as spherical, pyramidal or cuboid, free-floating colonies. Cells more-or-less densely alligned but usually with empty spaces between wall interstices. Cells globose, ovoid, or pyramidal 2-30 &m in maximum dimension. Cells joined at edges by specialized wall plaques…
Blue Green
Oscillatoria is a genus of filamentous cyanobacterium which is named after the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green. Oscillatoria is an organism…
Fresh Water Diatom
Gomphonema Colonial cells that form on branched muscilage stalks that are attached to a subtrate. In girdle view the cells are wedge shaped with an enlarged head at the opposite end of the stalk. Cells have one large plastid that lye mostly on one side of the girdle, but do extend partially onto the other…
Fresh Diatom
Pinnularia is a predominantly fresh-water alga, usually found in ponds and moist soil. They can also be found in springs, estuaries, sediments, and oceans. Pinnularia are elongated elliptical unicellular organisms. Their cell walls are composed chiefly of pectic substances on a rigid silica framework. Their walls are composed of two halves called thecae (or less…
Freshwater Algae
Ulothrix is a genus of green algae in the family Ulotrichaceae. Ulothrix is a genus of filamentous green algae, generally found in fresh and marine water. Its cells are normally as broad as they are long, and they thrive in the low temperatures of spring and winter. They become attached to surfaces by a modified…
Fresh water Diatom
he genus Synedra has long, needle-like cells that exist singly or in radiate colonies. In the colonies the cells are clustered together at one point by a mucilage cushion that is secreted from a pore field on each cell. Certain species have two short horns or spines protruding from the valve face just above the…
Live action of Bivalve Veliger under Foldscope.
Nalbana Sanctuary is an island protected for the millions of birds visiting every year from different parts of the world. It also harbours a huge number of benthic organism which acts as feed for the migratory birds. While doing ground survey for the planktons, the sample was taken and studied under the Foldscope. The pigmented…
Foldscopy of water boatman, a common bug.
During the southern sector sampling from the seagrasses dominated area, sediment samples were collected. We spotted a live organism in water samples and was immediately mounted and observed under foldscope. The organism was identified to be a water boatman. The water boatman, a common water bug, is a member of the ‘Corixidae’ family and order…
Foldscopy of green algae, Cladophora sp.
The Northern Sector of Chilika has tremendous amount influx of fresh water to the system and sheltering huge number of fresh water macrophytes and algae. During the ground survey of macrophytes in these area, dense growth of green algae was observed here. They were collected, mounted and observed under the Foldscope. The green algae were…

Pollinia of Calotropis under foldscope
Calotropis commonly called as Ak in native language is a milkweed because of the milky latex produced. Calotropis is a common weed found abundantly in North India. The peculiar thing about its pollen grains is the formation of Pollinia. Using a foldscope I could easily observe and understand the structure of a pollinium. From a Calotropis flower, I firstly…
An Impromptu Foldscope Workshop at TCIS, Hyderabad
The wild ivy grows wherever it pleases, said Marty Rubin. Although we have conveniently taken this quote from his dystopian novel, ‘The Boiled Frog Syndrome’, we have figured out that our excitement is in no way any less — it grows wherever it pleases, whenever it pleases, and also however it pleases. To feed this…
