The benefits ecosystems provide include food, water, timber, air purification, soil formation and pollination. But human activities are destroying biodiversity and altering the capacity of healthy ecosystems to deliver this wide range of goods and services

In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.
