Sharks belong to the classification known as Chondrichthyes i.e (cartilaginous fish) these fish have a flexible cartilage structure rather than bone. The Chondrichthyes mainly consist of 2 groups Holocephali and Elasmobranchii.

The major difference between Holocephalans and Elasmobranchs is the structure of the gills and also their growth rate in the embryo. The Holocephalans have 4-gill slits which are covered with a gill cover known as operculum on the other hand the Elasmobranchs have almost 5 to 7-gill slits which are not covered with any kind of gill cover. The Elasmobranch basically means naked gill.

The Elasmobranchii have 8 orders of sharks. These orders help us in understanding the sharks biological, physical attributes of the sharks.
