In addition to lizards and birds, the following organisms also have lungs:
Reptiles:
- Snakes
- Turtles
- Crocodiles
- Alligators
Mammals:
- Humans
- Dogs
- Cats
- Elephants
- Whales
- Bats
- Primates (e.g., monkeys, apes)
Additional Lung-bearing Organisms:
- Amphibians (like frogs and salamanders, although they primarily breathe through their skin as well)
- Some fish (like lungfish, which have evolved lungs to breathe air)
It's worth noting that while all of the listed groups primarily utilize lungs for respiration, there are variations in how they do so based on their habitats and evolutionary adaptations.
