Summary Introduction

To review:

The reason behind the early lineages of the living hagfishes and lampreys in the evolution of vertebrates along with their characteristics.

Introduction:

The notochord in lamprey is surrounded by cartilage, but notochord in hagfishes is not surrounded by any membrane. Both these fishes are eel-like and do not have fins.
