These are the vertebrates whose internal skeleton is made of cartilage, and these species contain no bones. Fish have different types of sensory organs such as lateral line system, olfactory system, eye, ampullae of Lorenzini, membranous labyrinth and specialized organs like electric organs, Weberian ossicles etc.Most fish have a faint line along the sides of their trunk that extends from the head to the tail. Many bony fish scales have been transformed to form a hard groove for the lateral line organ as well. 10th - 12th grade. eyes, lateral line system, electroreception. Biology.

Gills used for respiration. This lateral line is crucial in helping them get food and away from predators so that they do not become food. A bony skeleton. Egg development No. Pores for the receptors are visible around the snout and may be confused with those of the lateral line. Cartilaginous fish and jawless fish both, however, have gills, postanal tails, dorsal nerve cords that lead . Lateral Line. Lateral lines of bony fish are sensory organs that extend along both sides of their body. While sharks lack a swim bladder that many bony fish have, some species of shark, like the sand tiger . Fish Unit 29Q DRAFT. Cartilage is flexible and durable, yet is about half the normal density of bone. bony fish have a skeleton made of bone, have scales, covered gill slits . Therefore, the production of red blood cells takes place in the spleen. 3E, n=5): 50-65 days post-injection , all labelled PLL placodes had deposited clusters of DiI-positive cells along the trunk in a pattern recapitulating the distribution of trunk neuromasts .

Sharks, together with most fishes and aquatic and larval amphibians, also have a sense organ called the lateral line, which is used to detect movement and vibration in the surrounding water, and is often considered homologous to "hearing" in terrestrial vertebrates. Bony fish also tend to have symmetrical tails, while the tails of cartilaginous fish have upper lobes larger than the lower lobes. Lateral line system helps in searching food, in escaping from enemies and in orienting the body while swimming. Olfactory organs: Cyclostomes are monorhinic, i.e., they have a single, median olfactory organ. uncovered gill slits, no scales, lateral line: Term. have mostly ctenoid scales above the lateral line and cycloid below . The lateral line, also called lateral line system (LLS) or lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. What kind of ear do cartilaginous fish have. Answer: Cartilaginous fish (also called Chrondricytes) have a skeleton of cartilage, instead of bone. Gills, which are slits on both sides of fish that allow for respiration, or the exchange . Cartilage is flexible and durable, yet is about half the normal density of bone. These receptors make up the "lateral line," an organ similar in function to the ear that can feel pulses or vibrations in the water. A shark is the ultimate predator of the ocean and they have developed many adaptations to help them hunt, reproduce and survive in their marine environment. These organs are unique to fishes and help in knowing fluctuations in water quality,temperature, availability of food, and all sensory function. In this article we will discuss about the five main sensory organs of fishes with its respectively functions:- 1. The Inner Ear 3. Sharks and other cartilaginous fish (skates and rays) have skeletons made of cartilage and connective tissue. 1. 30 seconds . The single nostril opens behind into a rounded nasal or olfactory sac through a short duct. Q. The most important sense for cartilaginous fish is smell, in fact they have the ability to detect small amounts of substances and follow their trail easily. Cutaneous Senses. They also have specialized organs for capturing vibrations such as the lateral line. However, the sight is not specially developed in these animals. Sharks/relatives produce less offspring than other fish, but they are larger and typical survive longer. add a vertical curve to represent the gill cover, and a lateral line from head to tail. Multiple transformations of scales have occurred due to the urge to live, especially due to self-defense, food intake, etc. The bony fish have a membrane that covers the gill slits, while the cartilaginous fish have their gills exposed, without any protection. Sharks lack true bone but instead have cartilaginous skeletons that are much lighter. Fish have Kidneys has excretory organs. Sharks reproduce sexually, and eggs are fertilized internally. Sharks also have large livers full of low-density oils, which provide some buoyancy. The Eye: The fish eye is modified for the vision in air as well as in water. The zander (Sander lucioperca), sander or pikeperch, is a species of ray-finned fish from the family Percidae, which includes the perches, ruffes and darters. Lateral line. . They are supported only by the muscles. Bony fishes inhabit almost every body of water. The lateral line is visible as a darker stripe that runs along the length of the fish's body. The lateral line system, which most fish possess, allows them to detect waves of pressure or mechanical disturbances in the water. Where are bony fish found? Sharks need sensory mechanisms that can detect any prey (even at night). 1. The evolutionists seem surprised that natural selection would cause cartilaginous fish to lose the bones their putative ancestor had. The Eye 2. No external ears. an inner ear. Sharks have many close relations who, like themselves, have a skeleton made of cartilage rather than bone. Neuromasts help to sense water pressure and vibrations. class Chondrichthyes- sharks, skates, rays, ratfishes. How Do Cartilaginous fish Reproduce? Sharks belongs to a class of fish known as the Chondrichthyes or cartilaginous fish, which also includes rays, skates and chimera.. By developing well-refined senses that work in conjunction with dangerous speed, strength and . Electroreception has only been observed in aquatic or amphibious animals. The Olfactory Organs 5. located ventrally in cartilaginous fish. They use it to detect depth/water pressure, prey, pretators, sense current movement and orientation in the current, as well as to avoid collisions. CARTILAGINOUS FISH •Shark Characteristics: (continued) •Lateral line organs in sharks pick up sound vibrations over great distances •Sense of smell is very acute and can detect trace amounts of blood from over a half a kilometer away •Amullae of Lorenzini - sense electrical fields generated by muscles of fish and other potential prey 10. Thrashing made by dying or injured organisms. Two chambered heart. There is no lung or swim bladder is present. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical . They keep the fish steady while it swims. Probably not, but they do have them, located within their bodies as well as a lateral line system that actually lets them feel their surroundings. What does a swim bladder allow a bony fish to do that sharks cannot do? The Fish Heart has only two consecutive chambers called atrium and ventricle. Cartilaginous fish have a skeleton made up entirely of cartilage, while bone fish have a skeleton made up of bones. While Bony fishes excrete ammonia, cartilaginous fishes excrete Urea as nitrogenous waste. Cartilaginous fish do not have swim bladders, so a swimming motion must be maintained continuously, even when sleeping, or they will sink to the bottom. bMk, sfXYb, jTu, UBeq, zWxQKj, eMTn, OUaMBZ, ruuKx, VaFwx, julF, ECG, zEDT, QeDGtF,
