Question

List out characteristics of chordates ?.

Answer 1

Dear student

Chordata is the animal phylum which includes humans and other vertebrates. However, not all chordates are vertebrates.
Characteristics of Chordates:

• They are bilaterally symmetrical.
• They are triploblastic
• They are coelomate.
• They have paired gill pouches.
• Pharyngeal slits are present- a series of openings that connect the inside of the throat to the outside of the neck.
• Dorsal nerve cord is a prominent feature - a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.
• Notochord is present - cartilaginous rod running underneath, and supporting, the nerve cord.
• Post-anal tail is a characteristic feature - an extension of the body past the anal opening.
