Living Fossils: Fishes. Fishes are finned aquatic vertebrates, found abundantly in almost all bodies of water. As the first vertebrates (backboned animals) to evolve, they lack limbs. Fish-like animals first appeared all the way back in the Cambrian Period more than 500 million years ago. The strange jawless fishes that lived during the next.

The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
