Bioluminescent Phaeodarians
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. Bioluminescence occurs in multifarious organisms ranging from marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, dinoflagellates and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In most cases, the principal chemical reaction in bioluminescence involves the reaction of a substrate called luciferin and an enzyme, called luciferase. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin or cypridina luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin resulting in excited state oxyluciferin, which is the light emitter of the reac ...

Photinus Pyralis Firefly Glowing
Photinus (Greek: Φωτεινός; died 376) was a Christianity, Christian bishop of Sirmium in Pannonia Secunda (today the town Sremska Mitrovica in Serbia), best known for denying the incarnation of Christ, thus being considered a heresiarch by both the Catholic and Orthodox Churches. His name became synonymous in later literature for someone asserting that Christ was not God. His teachings are mentioned by various ancient authors, like Ambrosiaster (Pseudo-Ambrose), Hilary of Poitiers, Socrates Scholasticus, Sozomen, Ambrose of Milan, Augustine of Hippo, John Cassian, Sulpicius Severus, Jerome, Vigilius of Thapsus and many others. None of his writings are extant; his views must be reconstructed through his critics. Life Photinus grew up in Ankara, Ancyra in Galatia, where he was a student and later a deacon of bishop Marcellus of Ancyra, Marcellus. Marcellus, in later life a staunch opponent of Arianism, was excommunicated and deposed in 336 but rehabilitated by the Synod of Se ...
