Under water doesnt have enough air molucules that we need. Therefore we cant breath underwater. :)
An invertebrate doesnt have a backbone. A vertebrate has a backbone.
It is considered a fish because it is cold-blooded, has fins to help it swim and gills to help it breathe in water.Because they breath water not air.

Invertebrate paleontology
When you breath through your nose the air becomes warm and moisturized. through your mouth it doesnt. so the air stays cold and dry, which irritates your airways.
Its breath of fresh air.
A dog is a vertebrate because it has a backbone and a butterfly is a invertebrate because it doesnt have a backbone!
because water is how they breath and air is how we breath. we cannot breath in water so they cannot breath in air.
Yes. All humans breath a type of air called oxygen. Without oxygen we would die.
We get rid of waste when we breath out and when we breath in we take oxygen in to our lungs and breath.
