Mammals like Whales and dolphins live in Salt water. Some mammals like seals periodically live in water and than transfer to land.
None. Though the needs of all animals vary water is required in some quantity by all. There are some animals which get all or most from the food they eat but the requirement is still there.
the sea lions
Dog
not none
A fish is not a mammal or a reptile they have gills and live underwater plus they can not breath without water
animals that live in the water
Whales and dolphins are mammals and they live in the water so no, not all mammals live on land.
Otters are a semi-aquatic mammal. So they don't live exclusively in water.
A mammal can live on land and in the water, or sea.
A platypus.
I don't think that there is an animal that can live without water...A camel can live the longest without water but cannot completely live without water.... i will search this up but probaly germs
no grass can't live without water
On land - it is a mammal - not a fish or amphibian !
It isn't a "marine mammal" because it doesn't continuously live in salt water. A dolphin or whale, which never come ashore, is a "marine mammal". A platypus is an amphibious mammal, meaning that is capable of functioning in the water or on land.
you cant live without water or air
