The adaptations for the Barrel Cactus are ideal for their survival. Barrel Cacti have a unique metabolism that works for their lifestyle. Their metabolism lets the stomata remain closed in the daytime, which is when the most water would be lost. It then opens at night releasing the oxygen while absorbing the carbon dioxide that is normally saved as malate. The Barrel Cacti has a spine that doubles as a protective shield against its predators.

It hurts but if the spine is carefully removed, it should cause nothing more than a bit of discomfort.
actually, they are fall in the category of analogous groups. as they do the same function but have different structure.
Cacti might have had predators that would eat them in their new environment and cacti might have learn to adapt to that with their spine-formed leaves.
