The first vertebrates to come onto land were fish-like animals that developed lungs and could thus stay on land for extended periods. These evolved into terrestrial amphibians (although many amphibians require water in which to lay eggs, and some are aquatic).
The first land vertebrates appeared in the: Devonian
Vertebrates are animals with a backbone, so some vertebrates live in water (e.g. fish) but others live on land (e.g. cows).
they all have backbones and they have to live in water or in land
Amphibians were the first vertebrates that came out of the water. The first vertebrates that could live outside of the water though were reptiles. or class reptilia this was during the Carboniferous period.
Whales are an example of an animal with a spine that lives in the sea.
After fish, amphibians were the next group of creatures to evolve on Earth. Amphibians are cold-blooded vertebrates that can live both on land and in water. They were the first vertebrates to colonize terrestrial habitats.

Mammals,birds and reptiles are fully adapted to life on land. Fish live in water and amphibians start their life in water, then live on land.
Land and aquatic vertebrates are similar in that they both have a vertebral column. They are both either primary or secondary consumers as well. A difference is that vertebrates that live only in the water do not have fully developed hind legs.
