Olfactory morphology and physiology of elasmobranchs. The Chondrichthyes are the basalmost extant branch of Gnathostomata and comprehend a monophyletic group of fishes with fossils and extant representatives distributed in 65 families with 1282 valid species. The Wolffian ducts in males and Mullerian ducts in females become the functional urogenital ducts. [4], Like all other jawed vertebrates, members of Chondrichthyes have an adaptive immune system.[5]. Visual Neuroscience, 26(4), 397. https://doi.org/10.1017/S0952523809990150. Within the infraphylum Gnathostomata, cartilaginous fishes are distinct from all other jawed vertebrates. Cell and Tissue Research, 228(1), 139148. Sharks breathe chiefly by opening the mouth while expanding the mouth-throat (bucco-pharyngeal) cavity and contracting the gill pouches to close the gill slits. We've discovered that their brains aren't too different from ours in overall plan, although their cerebellum is quite large compared to the cerebrum in many cases, a reverse of our own brain setup. Mother produces up to 50 pups in each of two uteruses. Fish contain pain receptors called nociceptors like humans do. In addition to eating other fish, molluscs, and crustaceans, predatory fishes also feed on other species of fish. Kajiura, S. M. (2001). Differentiation is under hormonal control. Phylogenetic and ecological factors influencing the number and distribution of electroreceptors in elasmobranchs. The hindbrain contains the cerebellum, the part of the brain that controls movement and balance in humans. Springer, Cham. There are a number of vertebrates with jaws in the Gnathostomata division. Their nervous system adaptations range from the wild and electric, to the generalized lateral line system that helps their entire body function like an ear. 3. https://doi.org/10.1002/jmor.20106. As poikilothermic animals, they cannot regulate their internal body temperature. The forebrain connects to the midbrain by the diencephalon, a hormone-balancing structure. A., & Demski, L. S. (2004). Apart from electric rays, which have a thick and flabby body, with soft, loose skin, chondrichthyans have tough skin covered with dermal teeth (again, Holocephali is an exception, as the teeth are lost in adults, only kept on the clasping organ seen on the caudal ventral surface of the male), also called placoid scales (or dermal denticles), making it feel like sandpaper. Skates, which sometimes hold the lower surface of the head slightly above the bottom, may inhale some water through the mouth; mantas, which have small spiracles and live near the surface, respire chiefly through the mouth.

The Greenland shark (Somniosus microcephalus), which attains 6.5 metres (21 feet) or more (although rarely taken larger than about 4 metres [13 feet]), grows only about 7.5 mm (about 0.3 inch) per year.

Vertebrates comparative anatomy, function, evolution, 7th edn. In chondrichthyans, the nervous system is composed of a small brain, 8-10 pairs of cranial nerves, and a spinal chord with spinal nerves. Not all sharks are swimming noses: Variation in olfactory bulb size in cartilaginous fishes. Diverse species of fish are included in the class, such as sharks, rays, skates, and chimaeras. The class can be divided into two subclasses; Elasmobranchii (sharks, rays, skates, and sawfish) and Holocephali (chimaeras). All studies indicate a slow growth rate. As with all fish, sharks/relatives have a lateral line, which gives them a sixth sense to detect vibrations in water. Environmental Biology of Fishes, 61(2), 125133. Also, most chordates are dioecious, meaning that the males and females of species are different (''di . Active electroreception in Gymnotus omari: Imaging, object discrimination, and early processing of actively generated signals. A distinct heart, anteroventral to the liver, is enclosed in a pericardial sac.

Let's delve into the structure and function of the central nervous system in bony fish - the brain and spinal cord - as well as the peripheral nervous system - branching nerves that extend throughout the body. Meredith, T. L., Kajiura, S. M., & Hansen, A. Fertilization occurs internally. Humans depend on fishes for nutrition and micronutrients, which play a very important role in their diet as they control most diseases. With this, fishes can detect when the water around them moves, alerting them of a passing nearby fish. Kempster, R. M., McCarthy, I. D., & Collin, S. P. (2012). (Fun fact: Bull Sharks can live in both fresh and salt water and have been known spotted 4000km up the Amazon river, in Ganges river, the Mississippi, and in Lake Nicaragua! They are also produced in the Leydig's organ, which is only found in certain cartilaginous fishes. Environmental Biology of Fishes, 60(13), 4775.
