Cyclostomes are jawless ______.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. vertebrates.

  • Cyclostomes are jawless vertebrates.
  • The term "Cyclostomes" refers to a group of primitive, jawless fish that includes lampreys and hagfish.
  • These vertebrates are characterized by a round mouth (hence the term "cyclostome," which means "round mouth") and lack true jaws.
  • While they are vertebrates, they belong to a more primitive class compared to jawed vertebrates, such as fish with true jaws.
