"Green water" algae infestation. Green algae respond strongly to bright light conditions as well as unbalanced carbon dioxide and nutrient levels in the water of freshwater aquaria. [3] Green spot algae (GSA), most likely of the genus Coleochaete, is a spot-forming algae that slowly covers glass, aquarium furniture, and plants.
This calcified genus of Coralline algae encrusts shallow-water rocks, helping to build reefs by cementing dead coral together. It is pink-purplish in coloration and features irregular knobs. Fragments of the algae may be placed in aquariums to kickstart the growth of Coralline algae. [163] 10 in (25.4 cm) [163] Tattered sea moss: Hypnea pannosa ...
Coralline algae are widespread in all of the world's oceans, where they often cover close to 100% of rocky substrata. Only one species, Pneophyllum cetinaensis, is found in freshwater. Its ancestor lived in brackish water, and was already adapted to osmotic stress and rapid changes in water salinity and temperature.
The extinct Solenoporaceae have traditionally been interpreted as a group of red algae ancestral to the Corallinales. [4] The genus from which they take their name, Solenopora, originates in the Ordovician. [5] Unlike the Corallinaceae, this family has large vegetative cells and an undifferentiated thallus. [5]
These algae may be either zooxanthellae, zoochlorellae or both. The sea anemone benefits from the products of the algae's photosynthesis, namely oxygen and food in the form of glycerol, glucose and alanine; the algae in turn are assured a reliable exposure to sunlight and protection from micro-feeders, which the sea anemones actively maintain ...
This is a list of various species of marine invertebrates, animals without a backbone, that are commonly found in aquariums kept by hobby aquarists. Some species are intentionally collected for their desirable aesthetic characteristics. Others are kept to serve a functional role such as consuming algae in the aquarium.
Valonia ventricosa, also known as bubble algae, sea grape, [2] or sailor's eyeballs, [3] is a species of algae found in oceans throughout the world in tropical and subtropical regions, within the phylum Chlorophyta. It is one of the largest known unicellular organisms. [3] [4] Valonia ventricosa in the Red Sea
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
