Platypuses are not marine vertebrates. They can only live near fresh water.
Fish- only vertebrate that has gills its whole life Bird- Only vertebrate with feathers Reptile- Dry scaly skin Mammal- only vertebrate that doesn't lay eggs Amphibian- Spend half of their life in water
There isn't any. The simple separation of land and water vertebrates answers that question. Also, how specific are you tying to be, because mammals as a group can live pretty much anywhere, with a few exceptions of some more extreme environments. The only group of organisms capable of living in every known environment are Archaea, which are single celled prokaryotic organisms, but not vertebrates.
Mammals are the only vertebrate group which feed their young on mothers' milk.
There are thousands of such vertebrates as bony fishes .
No, it only has a notochord no vertebrae so it is only a Chordate not yet a vertebrate.
They are fish. They ONLY live in water.
Creatures that live only in water are referred to as aquatic.
Alone, the only cats that live in a family group (a pride) are Lions.
No seahorse can live in tap water they can only live in salt water
with their fins, they can only live in water the only way to live in water is if they can hold their breath or if they have gills
No because an amphibian lives in water and on land. Reptiles can only live in warm places like the desert.
