Vampyrella Velata
''Vampyrella'' is a genus of amoebae belonging to the vampyrellid cercozoans usually ranging from 30-60 µm. Members of the genus alternate between two life stages: a free-living trophozoite stage and a cyst stage in which mitosis occurs.RÖPSTORF, P., HÜLSMANN, N., & HAUSMANN, K. (1994). Comparative fine structural investigations of interphase and mitotic nuclei of vampyrellid filose amoebae. ''The Journal of Eukaryotic Microbiology, 41''(1), 18-30. doi:10.1111/j.1550-7408.1994.tb05930.x This taxon has received a great deal of attention due to their peculiar feeding behaviour of perforating the cell wall of algal cells and drawing out the contents for nourishment. History Vampire amoebae were first discovered in 1865 by Leon Cienkowski. These amoebae were given the genus name ''Vampyrella'' due to their bright red colouration and their distinct feeding habits in which they perforate the cell wall of their host and draw out the inner contents of the cell, resembling that ...

Vampyrella Lateritia
''Vampyrella lateritia'' is a freshwater species of predatory amoebae that feeds on species of algae and is known for its specialized feeding strategy of removing, digesting, and ingesting the cellular contents of its prey. It is the type species of the genus ''Vampyrella'' and has been identified in numerous locations around the world including Brazil, Germany, and the eastern United States. Along with ''Vampyrella pendula'', its genome was sequenced in 2012. Life cycle ''Vampyrella lateritia'' has four life stages that revolve about the feeding cycle: motile trophozoites (the activated, feeding stage), plasmodia in which the cytoplasm contains many nuclei, digestive cysts, and resting cysts. It has been observed feeding on species from the genera '' Zygnema'', ''Spirogyra'', and '' Mougeotia'' and is considered a specialist predator as its known prey is restricted to a limited number of green algal species. Like other vampyrellids, ''Vampyrella lateritia'' grows well bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microalgae
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. Unlike higher plants, microalgae do not have roots, stems, or leaves. They are specially adapted to an environment dominated by viscous forces. Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use the greenhouse gas carbon dioxide to grow photoautotrophically. "Marine photosynthesis is dominated by microalgae, which together with cyanobacteria, are collectively called phytoplankton." Microalgae, together with bacteria, form the base of the food web and provide energy for all the trophic levels above them. ...

Spirogyra
''Spirogyra'' (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. ''Spirogyra'' species, of which there are more than 400, are commonly found in freshwater habitats. ''Spirogyra'' measures approximately 10 to 100 μm in width and may grow to several centimetres in length. It is often observed as green slimy patches on the ground near ponds and other water bodies having stagnant water. General characteristics ''Spirogyra'' is very common in relatively clear eutrophic water, developing slimy filamentous green masses. In spring ''Spirogyra'' grows under water, but when there is enough sunlight and warmth they produce large amounts of oxygen, adhering as bubbles between the tangled filaments. The filamentous masses come to the surface and become visible as slimy green mats. ''Spirogyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
