Ray-finned fishes

Members of the family Gobiesocidae are considered to be ray-finned fish because their fins have one spine and four or five rays. Each fish in the family has a single dorsal fin that is positioned nearer to the tail than to the head, as well as an anal... 

Table 4.1 presents a classification of fishes derived from Nelson (1994) in order to indicate the taxonomic position of the species studied. This classification puts the fishes in an order that reflects their postulated evolutionary relationship, ranging from the most ancient splits in vertebrate evolution, Chondrichthyes (sharks, rays), Sarcopterygii (Lung-fish, Coelacanths and Tetrapods) and Actinopterygii (ray-finned fishes), to the most recent teleost orders, Pleuronectiformes (flounders) and Tetraodontiformes (puffers).
