The cartilaginous fishes (Class Chondrichthyes) comprising chimaeras, sharks, skates, and rays are the oldest living group of jawed vertebrates that diverged from a common ancestor of bony vertebrates (Osteichthyes: ray-finned fishes, coelacanths, lungfishes, and tetrapods) in the early Silurian about 420 Ma (Benton et al. The world`s largest member of Chondrichthyes is the plankton-feeding whale sharks (Rhincodon typus) which can grow up to 18 meters (60 feet) in length with 21.5 tonnes in weight and live up to 130 years. Fish are the cold-blooded aquatic organisms which belong to the subphylum Vertebrata of phylum Chordata. This category of fish is also referred to as Teleostomi. They excrete urea as the nitrogenous waste product. They have 4 pairs of gills or breathing organs which are covered by the gill covers or the operculum on each side. A fÅ különbség a Chondrichthyes és az Osteichthyes között az, hogy a Chondrichthyes a csontos halak osztálya, amelynek endoszkeleton porcokból áll, míg Osteichthyes a porcos halak osztálya, amelynek endoszkeleton csontokból áll.Ezenkívül a Chondrichthyes csak a tengervízben található, míg az Osteichthyes a friss és a tengervízben egyaránt megtalálható. They may be oviparous (egg layers), viviparous (live-bearer) or some species are ovoviviparous (mother carry eggs in her body). Owing to their phylogenetic position, chondrichthyans provide a critical reference for our understanding of vertebrate genome evolution.

The cartilaginous fishes (Class Chondrichthyes) comprising chimaeras, sharks, skates, and rays are the oldest living group of jawed vertebrates that diverged from a common ancestor of bony vertebrates (Osteichthyes: ray-finned fishes, coelacanths, lungfishes, and tetrapods) in the early Silurian about 420 Ma (Benton et al. Their heavy weight could crush the internal organs outside water (e.g. Chondrichthyes fish have a cartilage skeleton with no bone while osteichthyes fish have a bony skeleton.
