The fact that jawless fish retain the notochord during development suggests that jawed vertebrates have evolved to develop without the notochord. This indicates that the notochord is an ancestral characteristic that has been lost or modified in the evolutionary lineage leading to jawed vertebrates.
What vertebrate has a reproductive cycle that depends on water?
Amphibians and fish are both vertebrates which rely on water for their reproductive cycle.
It depends on the animal! Some reproduce by laying eggs, others by live birth.
Is a herring a invertebrate or a vertebrate?
As it stands, the answer is no, but, the hagfish status is still a little up for debate because it seems that they MAY have once had a vertebrate but then lost it through further specialization. They are the only animal to have a skull without a vertebrate.
Also, the hagfish's "skeleton" is not bone, but a softer, but still stiff, substance such as cartilage but not cartilage.
What group of vertebrates begins life in water and later lives on land?
Hi, that sounds like the group called Amphibians. This group includes frogs, most of which start out life as tadpoles that swim in water. As they get older they lose their tails and grow arms and legs. Then they can live on land, although they usually don't get too far away from water.
