How Do Sharks Differ From Other Fish Types?
The majority of people most consider a shark swimming creature with huge blades and sharp teeth. On the planet today, various sorts of sharks exist and are divided into groups. Sharks altogether belong to a unique group called Class Chondrichthyes.” New different kinds of sharks belong to this Class, “Elasmobranchii.” For the most part, these are marine fish, implying that they live in saltwater. There is an imminent threat of shark extinction because of overfishing. The population of many species has declined by up to 80% since the 1980s. It is essential for healthy oceans to have healthy shark populations because they maintain the balance of the marine food chain. The shark has a slow growth rate and produces few young, which makes them highly vulnerable.
Skeletons of sharks consist of cartilage without real bones. They have “pectoral fins” through which they swim forward only. Upward movement is impossible for them. For breathing, they keep swimming. Among other main differences, cartilaginous fish are distinguished by a unique tooth attachment and replacement type.
In comparison with fish having bones, both males and females excrete sperm and eggs in water to mingle, and these fish have internal fertilization. Male sharks have “cartilaginous” organs called claspers. These are modified parts of the pelvic fins inserted in the female cloaca. Sperms are placed inside the female during copulation. Compared to fish having bones, Chonrichthyans mature at a young age.
