The skull also encloses the brain, always comprising five parts referred to as the rhombencephalon, metencephalon, mesencephalon, diencephalon, and telencephalon. The metencephalon is developed into a cerebellum in the Gnathostomata and some fossil jawless vertebrates. The nerve fibres are primitively non-myelinated and become myelinated only in the gnathostomes. The brain is continued posteriorly by the spinal cord, which is ribbon-shaped but becomes thicker in the gnathostomes. As in cephalochordates, the dorsal (sensory) and ventral (motor) spinal nerves are initially separate, but unite in the gnathostomes. In all craniates, the olfactory (I), optic (II), trigeminal (V), facial (VII), acoustic (VIII), glossopharyngeal (IX) and vagus (X) cranial nerves are present. Additional cranial nerves, the oculomotor (III), trochlear (IV) and abducent (VI) nerves occur only in the Vertebrata. Some consider that the latter have been secondarily lost in hagfishes.. The olfactory organ opens into a median ...

Actinopterygii (the plural form of Actinopterygius) is commonly placed as a class of vertebrates (ITIS 2017; Jonna 2004; Nelson 1994), generally with the parent taxon Osteichthyes (the bony fish) listed as a superclass. In some classification schemes, however, Osteichthyes is listed not as a superclass but as a class, in which case Actinopterygii is listed as a subclass. Alternatively, Nelson (1994), while using Actinopterygii as a class, chooses not to use Osteichthyes as a formal taxon at all because it "is clearly not a monophyletic group." With such a great multitude of species, the Actinopterygians characteristics tend to be spread over a considerable range. Many, but not all, of the Actinopterygians, for example, have scales, which may be either the more primitive ganoid form(diamond-shaped, shiny, hard, and multilayered), or the more advanced cycloid or ctenoid forms, which overlap a bit like roof tiles from head to tail to reduce drag. Cycloid scales have smooth edges and ctenoid have ...

The extreme level of polymorphism in its population has inspired novel approaches in genome assembly, which we here continue to develop. Specifically, we present the re …
