Siamese fighting fish were originally given the scientific name Macropodus pugnax in 1849—literally "aggressive fish with big feet", likely in reference to their elongated pelvic fins. [ 14 ] In 1897 they were identified with the genus Betta and became known as Betta pugnax, referring to their aggressiveness.
Oshimia D. S. Jordan, 1919. Pseudobetta Richter, 1981. Betta / ˈbɛtə / is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (Osphronemidae). [1] The best known Betta species is B. splendens, commonly known as the Siamese fighting fish and often kept as an aquarium pet.
The Betta Cracens have a Labyrinth Organ, a morpho-physiological adaptation that allows them to respirate in air. The Labyrinth Organ is a folded suprabranchial accessory breathing organ and a defining characteristic of fish in the suborder Anabantoidei. It is formed by vascularized expansion of the epibranchial bone of the first gill arch.
Celery was probably a typical pet store Betta fish. She was blue with pink tinged-fins, not as iridescent or full-finned as some of her plastic tanked neighbors, but healthy looking enough.
The peaceful betta or crescent betta (Betta imbellis) is a species of gourami native to Southeast Asia. Betta imbellis has a pair of suprabranchial chambers that each house a labyrinth organ, a complex bony structure lined with thin, highly vascularised respiratory epithelium. The labyrinth organ is a morpho‐physiological adaptation that ...
Fish reproduction. A pair of bettas spawning under a bubble nest. Fish reproductive organs include testes and ovaries. In most species, gonads are paired organs of similar size, which can be partially or totally fused. [1] There may also be a range of secondary organs that increase reproductive fitness.
Vision is an important sensory system for most species of fish. Fish eyes are similar to those of terrestrial vertebrates like birds and mammals, but have a more spherical lens. Their retinas generally have both rod cells and cone cells (for scotopic and photopic vision), and most species have colour vision.
As labyrinth fish, Betta mahachaiensis have a pair of suprabranchial chambers that each house an air-breathing organ known as the labyrinth organ, a complex bony structure lined with thin, highly vascularised respiratory epithelium. The labyrinth organ is a morpho-physiological adaptation that allows labyrinth fish to extract oxygen from air. [3]
