Chiton vs. Tunic

Main Difference

The main difference between Chiton and Tunic is that the Chiton is a class of molluscs and Tunic is a simple T-shaped or sleeveless garment, usually unfitted, of archaic origin

• Chiton

  Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.

  They are also sometimes known as sea cradles or “coat-of-mail shells”, or more formally as loricates, polyplacophorans, and occasionally as polyplacophores.

  Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle.

• Tunic

  A tunic is a garment for the body, usually simple in style, reaching from the shoulders to a length somewhere between the hips and the knees. The name derives from the Latin tunica, the basic garment worn by both men and women in Ancient Rome, which in turn was based on earlier Greek garments that covered wearers’ waists.
