The sharks are of the greatest interest to the morphologist on account of the many ancestral characters of their organization. The researches of recent years indicate that they represent quite well the primitive stem of the jaw-bearing vertebrates. With this fact in mind, the importance of the study of the shark's brain is at once apparent. For obvious reasons modern neurological investigation has been largely concerned with the mammalian brain in general and the human brain in particular. But the structures here are highly specialized, and their significance cannot always be thoroughly understood. In order to unravel the tangled threads of the complex neurological skein, the study of some primitive type of brain is an absolute necessity. The brain of the shark is the one to which we naturally turn for this purpose because of the morphological position which it occupies.
