The phycobilisome components (phycobiliproteins) are responsible for the blue-green pigmentation of most cyanobacteria. [77] The variations on this theme are due mainly to carotenoids and phycoerythrins that give the cells their red-brownish coloration. In some cyanobacteria, the color of light influences the composition of the phycobilisomes.
Klamath AFA is a blue-green algae that has been harvested wild from Upper Klamath Lake since the 1980s and used as a dietary supplement. [2] [3] Genome sequencing distinguished and named this isolate as Aphanizomenon flos-aquae MDT14a, [4] [5] distinct from other varieties of Aphanizomenon flos-aquae.
The endosymbiotic green algae may have been acquired through myzocytosis rather than phagocytosis. [23] (Another group with green algae endosymbionts is the dinoflagellate genus Lepidodinium, which has replaced its original endosymbiont of red algal origin with one of green algal origin. A nucleomorph is present, and the host genome still have ...

[4] [5] For example, a large marine vertebrate may eat smaller predatory fish but may also eat filter feeders; the stingray eats crustaceans, but the hammerhead eats both crustaceans and stingrays. Animals can also eat each other; the cod eats smaller cod as well as crayfish, and crayfish eat cod larvae. The feeding habits of a juvenile animal ...
The prefix cyan comes from the Greek κύανoς meaning "a dark blue substance", [19] and usually indicates any of a number of colours in the blue/green range of the spectrum. Cyanobacteria are commonly referred to as blue-green algae. Traditionally they were thought of as a form of algae, and were introduced as such in older textbooks.
Green algae are also found symbiotically in the ciliate Paramecium, and in Hydra viridissima and in flatworms. Some species of green algae, particularly of genera Trebouxia of the class Trebouxiophyceae and Trentepohlia (class Ulvophyceae), can be found in symbiotic associations with fungi to form lichens. In general the fungal species that ...
Blue green algae growing on the substrate of a fresh water aquarium. Although colloquially called algae, blue-green algae (BGA) is a type of cyanobacteria. It can present with several different colors. While there are many BGA species, the most common type found in aquaria is referred to as "slime algae".
