Fish is not just crucial to the ecosystem but is also very important to us as it provides the body with many nutrients and micronutrients. Humans depend on fishes for nutrition and micronutrients, which play a very important role in their diet as they control most diseases. Both freshwater and marine species fall into these classes. It is possible for them to be oviparous, viviparous, or ovoviviparous.Р”Р„ccording to the structure of the endoskeleton, Pisces has two types of classes: the Chondrichthyes and the Osteichthyes. The General Characteristics of Chondrichthyes and OsteichthyesР”В¬hondrichthyes and Osteichthyes have the following general characteristics:Р”В«oth have endoskeletons and exoskeletons. They are oviparous in some cases and viviparous in others. In females, the cloaca serves both as a reproductive organ and as an excretory organ.Р”Р‡ertilization occurs internally. This also helps the animals to prey on one another.Р”В¬hondrichthyes digestive system: The stomach, pharynx, mouth, intestines, and cloaca make up the digestive system. To defend themselves from enemies, they possess poison stings. The sharks of the Chondrichthyes family possess special sense organs on their heads called electroreceptors that aid them in detecting prey and orienting themselves to their prey.

Two chambered hearts, one with an auricle and one with a ventricle, are present in these creatures.Р”Вespite the vertebral column protecting their brains and spinal cords, chimpanzees have developed. In addition to eating other fish, molluscs, and crustaceans, predatory fishes also feed on other species of fish. The lack of air bladders means they need to swim constantly to avoid sinking.Р”Р„s poikilothermic animals, they cannot regulate their internal body temperature. There are placoid scales covering the skin.Р”В®ach gill has between five and seven blades. A distinct heterocercal tail protrudes from the lower lobe as well as the extension of vertebrae into the upper lobe. Whale sharks, the second-largest vertebrae and the largest fish, measure up to 15 meters in length.Р”В¬alcium deposits provide strength to the endoskeleton, which is composed of cartilage.Р”В«esides the elongated upper lobe, the tail consists of two shorter lobes. It includes Chimaeras, also known as ghost sharks.Р”В¬artilaginous fish have the following characteristics:Р”Р„mong the Chondrichthyes are powerful jaws that are found in marine fish. Holocephali: The word Holocephali means РІР‚Вcomplete headРІР‚в„ў. It includes sharks and rays, skates, and sawfishes. Chondrichthyes is further subdivided into two subclasses:Р”В®lasmobranchii: In Greek, elasmo means РІР‚ВPlateРІР‚в„ў and branchia means РІР‚ВgillРІР‚в„ў, hence we can tell that long and broad flattened gills are the characteristics of these fishes. The class Chondrichthyes means a class that contains cartilaginous fishes whose skeleton is composed of cartilage. IgnoreWarnings = true Return 0 // ignore Case d.Chondrichthyes in the Greek language has the following meaning, chondr means РІР‚ВCartilageРІР‚в„ў and ichthyes means РІР‚ВFishРІР‚в„ў. Return 0 // ignore Case d.AlternateActionButton
