Neither. It is a fish. That is why it is called a “Puffer fish.”

∙ 11y agoReptiles, birds, mammals and most adult amphibians have lungs , but young amphibians have gills rather than lungs. Some amphibians retain gills for all their lives. Some salamanders lack lungs and breath through their skin. Most fish have gills and not lungs, though there are lungfish.

∙ 11y agoAmphibians have third heart chamber and a double circuit pump. This third chamber helps to keep the oxygenated and deoxygenated blood separate. The oxygenated blood from the lungs enters the left atrium while the deoxygenated blood from the tissues arrives at the right atrium. The blood is then emptied into the single ventricle which allows some of oxygenated blood to mix with the deoxygenated blood as it is being pumped to the lungs and tissues.
Lungfish, however are the closest living aquatic relatives to amphibians. They only have a single atrium that is partially divided by an interatrial septum.

What is the breathing method of mammals birds reptiles amphibians fish?
Mammals, birds, reptiles and adult amphibians breathe using lungs. Fish breathe using gills, while juvenile amphibians breathe using gills and spiracles.
What non mammals breathe through lungs?
Birds, reptiles and most amphibians breathe through lungs.
Do mammals have gills or lungs?
Mammals have lungs, as do amphibians, reptiles, and birds. Fish are the only chordates that have gills rather than lungs.
Do amphibians or reptiles always breathe with lungs?
Reptiles always breathe with lungs. Amphibians may breathe with lungs, gills or through their skin.
Does a possum breathe through lungs?
Yes. Possums are mammals, and all mammals breathe through lungs, just as birds, reptiles and adult amphibians do.
Do amphibians and reptiles breathe with lungs?
yes
Which animals have lungs?
Most land vertebrates including all birds, mammals, and reptiles have lungs. Most amphibians have lungs as well, though some salamanders breathe through their skin or through gills. A few types of fish have lungs as well Spiders and gastropods and among the few invertebrates to have lungs. Most breather passively through spiracles, their skin, or through gills.
What are the groups of vertabrates?
Here they are, from oldest to most recent on the evolutionary tree. In parenthesis after the groups are major adaptions which distinguish a group from the one that came before it. Fish Amphibians (lungs in adult stage) Reptiles (lungs) Birds (warm-blooded) Mammal (give birth to live young)
How do the eggs of birds and reptiles differ?
A reptile egg is much much much softer than birds egg.
Which class of animals are cold blooded breathe with lungs have scales and lay eggs?
Reptiles, amphibians and fish are all cold-blooded vertebrates.
What kind of lungs do reptiles have?
When amphibians are babies, they have gills, but most adult amphibians breathe with a pair of lungs excluding salamanders.
What is an animal that is cold blooded and is a vertebrate?
Coldblooded vertebrates include the fish, the amphibians and the reptiles. There are a actually fish with lungs, lungfish. Some species of lungfish have more or less working gills, but most species need to breath using their lung(s) even when in the water. Amphibians all have a juvenile water-breathing form, no exceptions to my knowledge. Their adult form has lungs. Reptiles (crocodiles, snakes, lizards, turtles) are the group you are probably looking for. These breath using their lungs.
