Which vertebrate lays its eggs on land? a. lizard b. frog c. newt d. catfish

A lizard :)

Explanation:Frogs lay there eggs in the water for example a underwater stick. Newts also lay there eggs underwater or in a underwater enviroment. And catfishes also lay they eggs under water. Where i live (Florida) there are millions of lizards and sometimes i find them on the ground or on land. I also did some research and its a fact that lizerds do in fact lay there eggs on the ground.

I really hope this helps have a great rest of your day :) :) :) :) :)
