OSTARIOPHYSI Meaning and
Definition
-
Ostariophysi, also known as the otophysans, is a diverse group of fish belonging to the class Actinopterygii, which includes the majority of ray-finned fish species. The name Ostariophysi is derived from the presence of the Weberian apparatus, a characteristic unique to this group. This apparatus consists of a series of small bones that connect the swimbladder to the inner ear, enhancing their hearing capabilities.
Ostariophysi encompasses a wide variety of fish species, notably including the popular aquarium inhabitants such as the tetras, catfish, and characins. It includes both freshwater and brackish species that can be found in a variety of habitats worldwide, including rivers, streams, lakes, and even coastal regions. Ostariophysi display a range of morphological and behavioral adaptations, depending on their ecological niche and environment.
One prominent feature of ostariophysan fish is the presence of a specialized sense organ called the lateral line system. This system allows them to detect movements and vibrations in the surrounding water, aiding in navigation, prey detection, and communication with conspecifics. Additionally, many members of this group possess a unique reproductive strategy known as internal fertilization, where the male transfers sperm to the female’s body rather than releasing it into the water.
Overall, Ostariophysi is a taxonomic group that comprises a diverse array of fish species sharing several common characteristics. Their remarkable adaptations, ranging from the Weberian apparatus to the lateral line system, have played a crucial role in their successful evolutionary diversification and their ability to thrive in various aquatic environments.

Etymology of OSTARIOPHYSI
The word "ostariophysi" is derived from two Greek words: "osteon" meaning "bone", and "ophis" meaning "snake". The term was coined by the French ichthyologist Charles Lucien Bonaparte in 1846 to describe a group of fish species characterized by a specific arrangement of bones in their mouths. The name was given due to the resemblance of these fish species' jaws to the jaws of a snake.
