2. Secondarily aquatic tetrapods - Wikipedia

   en.wikipedia.org/wiki/Secondarily_aquatic_tetrapods

   Several groups of tetrapods have undergone secondary aquatic adaptation, an evolutionary transition from being purely terrestrial to living at least part of the time in water. These animals are called "secondarily aquatic" because although their ancestors lived on land for hundreds of millions of years, they all originally descended from ...

3. Skeletal changes of vertebrates transitioning from water to land

   en.wikipedia.org/wiki/Skeletal_changes_of...

   Phylogenetic analyses distribute the features that developed along the tetrapod stem and display a stepwise process of character acquisition, rather than abrupt. [1] The complete transition occurred over a period of 30 million years beginning with the tetrapodomorph diversification in the Middle Devonian (380 myr). [2]

4. Marine vertebrate - Wikipedia

   en.wikipedia.org/wiki/Marine_vertebrate

   Both cetaceans and sirenians are fully aquatic and therefore are obligate water dwellers. Seals and sea-lions are semiaquatic; they spend the majority of their time in the water, but need to return to land for important activities such as mating, breeding and molting. In contrast, both otters and the polar bear are much less adapted to aquatic ...

5. Tulerpeton - Wikipedia

   en.wikipedia.org/wiki/Tulerpeton

   Tulerpeton is one of the early transition tetrapods – a marine animal capable of living on land. The separation of the pectoral-shoulder girdle from the head allowed the head to move up and down, and the strengthening of the legs and arms allowed the early tetrapods to propel themselves on land.

9. Evolution of tetrapods - Wikipedia

   en.wikipedia.org/wiki/Evolution_of_tetrapods

   The evolution of tetrapods began about 400 million years ago in the Devonian Period with the earliest tetrapods evolved from lobe-finned fishes. [1] Tetrapods (under the apomorphy-based definition used on this page) are categorized as animals in the biological superclass Tetrapoda, which includes all living and extinct amphibians, reptiles, birds, and mammals.
