The ground sharks, order Carcharhiniformes, are the largest order of sharks; they are also called whaler sharks. Sharks ( Superorder Selachimorpha) are a type of Fish with a full cartilaginous Skeleton and a highly streamlined body With over 270 species, carcharhiniforms include a number of common types, such as the blue shark, catsharks, swellsharks, and sandbar shark. The blue shark, Prionace glauca, is a Carcharhinid Shark which is found in the deep waters of the world's Temperate and Tropical The sandbar shark, Carcharhinus plumbeus, comes from the Carcharhinidae family of Sharks also called Requiem sharks The sandbar shark
Members of the orders are characterized by the presence of a nictitating membrane over the eye, two dorsal fins, an anal fin, and five gill slits. The nictitating membrane is a transparent or Translucent third Eyelid present in some animals that can be drawn across the Eye for protection and to moisten A dorsal fin is a Fin located on the backs of some Fishes Whales Dolphins and Porpoises as well as the (extinct The Anatomy of Fish is primarily governed by the physical characteristics of Water, which is much denser than air holds a relatively small amount of dissolved A gill is an anatomical structure found in many aquatic organisms
The families of the carcharhiniforms are expected to be revised; recent DNA studies show that some of the traditional groups are not monophyletic. Deoxyribonucleic acid ( DNA) is a Nucleic acid that contains the genetic instructions used in the development and functioning of all known A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor
