Give scientific classification of shark up to class answer in brief

The Correct Answer and Explanation is:

Scientific Classification of Shark (up to Class):

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Chondrichthyes

Explanation
Sharks are a diverse group of fish known for their cartilaginous skeletons, streamlined bodies, and often predatory behavior. Their scientific classification begins at the broadest level with Kingdom Animalia, which includes all multicellular, eukaryotic organisms that are heterotrophic, meaning they rely on consuming other organisms for energy. Animals in this kingdom are capable of movement at some point in their lives and possess specialized sensory organs.

Moving to Phylum Chordata, sharks are part of a group of animals that, at some stage in development, possess a notochord, a dorsal nerve cord, pharyngeal slits, and a post-anal tail. In sharks, these features are evident especially during their embryonic development, though many persist into adulthood. The presence of a spinal cord protected by vertebrae places them in this phylum alongside mammals, birds, reptiles, amphibians, and other fish.

Sharks fall under the Class Chondrichthyes, which is a class of cartilaginous fishes. This class includes both sharks and rays. Unlike bony fish in the class Osteichthyes, Chondrichthyes have skeletons made entirely of cartilage, a tough yet flexible connective tissue. This adaptation makes them lighter and more agile in the water. Members of this class also typically have placoid scales, which are small, tooth-like structures that reduce friction and provide protection. They possess five to seven gill slits on each side of their head and do not have swim bladders. Instead, their buoyancy is maintained through large oil-filled livers.

Sharks have existed for over 400 million years, making them one of the oldest surviving vertebrate lineages. Their evolutionary success is attributed to their efficient sensory systems, such as electroreception, keen smell, and acute vision. These adaptations help them detect prey and navigate their environment, reinforcing their role as apex predators in many marine ecosystems.
