You have the amphibians which are born in the water and grow into air breathing creatures, (such as the frog). Then there are the aquatic vertebrates which are wholly, or chiefly, water living creatures.
Fish live in water because their bodies are specially adapted to survive and thrive in aquatic environments. Their gills extract oxygen from the water, allowing them to breathe, and their streamlined bodies and fins help them move swiftly through the water. Additionally, water provides buoyancy to support their bodies, making it easier for them to swim and navigate their surroundings.
they use paired fins to move through water(:
Fish ;)
They use there fins
Fish or if you are talking about dolphins and whales then mammals as well but mostly fish
It is a fish, not a mammal.Fish lives is a aquatic vertebrate, lives in a water, breath with gills, and most of them are cold-blooded, allowing their body temperatures to vary as ambient temperatures change.Mammals are members of air-breathing vertebrate animals, have a placenta which feeds the offspring during gestation.
Mudskippers do not experience any ill effects in clear water. Their name is a reference to their ability to cross expanses of mud with their strong fins.
A fish is a cold-blooded vertebrate that live entirely on water. Some of its adaptations include: gills and fins, tails, lateral lines and numerous number of offspring.
The term for a class that means two lives is "amphibian." Amphibians are vertebrate animals that can live both in water (during their early stages of life) and on land as adults.
A water rocket should probably have three to four fins.
Water rockets need fins because the rocket needs to stay in balance....without fins on a water rocket, the water rocket would be going out of control because it is not in balance!
Difference between an ant and fish. A fish is a cold-blooded vertebrate animal that lives in water, moving with the help of fins and breathing with gills while an ant is any of various insects in the family Formicidae in the order Hymenoptera, typically living in large colonies composed almost entirely of flightless females.
