Many fish species also use paired fins for locomotion. Fins are supported by a bony skeleton and are powered by sets of muscles. Depending on fin size and shape, fish use them to produce forces that control the body. In this way, fins are used for both propulsion and maneuvering....

Paired fins are a major innovation1,2 that evolved in the jawed vertebrate lineage after divergence from living jawless vertebrates3. Extinct jawless armoured stem gnathostomes show a diversity of paired body-wall extensions, ranging from skeletal proces
To solve the question "Paired appendages are not found in," we need to analyze the options provided: hemichordates, urochordates, cephalochordates, and all of these. 1. Understanding Paired Appendages: - Paired appendages refer to limbs or structures that come in pairs, such as fins or leg...
