Sample text

Most recently, however, molecular studies have not corroborated the morphological evidence. Instead, these studies suggest that the hagfishes and lampreys may indeed be each other’s closest relative, in which case the “Cyclostomata” would be monophyletic. 2). As noted above, a major feature of craniates is the development of a “true” head. A distinct anterior enlargement of the nervous system, forming a brain, and of sensory organs occurs in craniates. The brain of craniates is tripartite, with three main primary subdivisions; and the specialized sense organs—eyes, ears, and nose—are complex.

In this system, the upper jaw was fused to the braincase. The upper and lower jaws were long, with the articulation far back under the skull, permitting a wide gape. These features are reflected by the orientation of the hyomandibula, which sloped posteroventrally. The feeding apparatus underwent modifications, resulting in a complex kinetic system in which the jaws are protruded and allow inertial suction feeding. The main anatomical changes are that the jaws shortened, so the hyomandibula swung forward to assume, in advanced teleosts, an anteroventral orientation.

Also, the body is, again as in sharks, fusiform, or torpedo-shaped. These features make for fast swimming. In teleosts, the pectoral fins are moved dorsally and the pelvic fins anteriorly. The tail is homocercal (superficially symmetrical) and the body laterally compressed. These changes allowed for different swimming styles, with considerably more precision control (for example, the dorsal position of the pectoral fins allows them to function as “brakes”). These changes were also instrumental in the great radiation of actinopterygians.
