Many frogs and salamanders start their lives with gills, but when they grow they develop lungs.
There is no such mammal.
amphibian
one of them are the gills of fish.hope this helps.
Lungs a similar in that they help to bring oxygen into the living things body. The difference is that gills are external and lungs are internal.
Animals do not get rid of oxygen- they consume it. They get rid of carbon dioxide by exhaling it from their lungs (or gills).
Neither, in general lungs are only good for animals that breath air and fins are used for swimming not breathing. In a water environment, oxygen exchange is accomplished using organs called "gills" and fish have gills.
Most animals breathe throught there mouth and nose. Other animals like Whales, Dolphins,. etc. breathe through air holes. Water animals, breathe water through gills. and often suface for oxygen.(Again through mouth or air hole; depending on the animal.)
The only animal that has true lungs and gills is the lungfish. Animals like frogs often have gills for a portion of their lives and then later develop lungs.
they actuly all have lungs but fish gave gills
A kangaroo breathes with its lungs. A kangaroo does not have gills, animals that need to breath in water are the ones with gills.
lungs or gills
No, not all animals have lungs, fish and reptiles have gills, humans and mammals have lungs except whales and dolphin they have gills because they under water
Frogs are born with gills, but soon, when they get older, they get lungs, and start breathing oxygen.
amphibians use gills AND lungs, fish/marine life use gills alone
Animals = lungs Fish = gills
Lungs for air breathing animals Gills for water breathing animals
Animals breathe in many ways: through body coverings, gills,tubes in their body, and lungs.some with lungs others with gills
Lungs and gills help animals breathe by taking in oxygen and than releasing carbon monoxide.
A tadpole can breath through their gills but they grow lungs as they turn into a frog.
