Here's a breakdown:
* Quadri- means "four"
* -ped means "foot"
Therefore, "quadriped" literally means "four-footed."
Examples of quadrupeds include:
* Mammals: Dogs, cats, horses, cows, elephants
* Reptiles: Lizards, snakes, crocodiles
* Amphibians: Frogs, toads
* Insects: Some beetles, spiders
It's important to note that some animals may walk on four legs but are not technically quadrupeds, like some primates, which walk on all fours but are classified as bipedal because they are primarily upright walkers.
