Internet personality and model Olivia Ponton is basking in her success -- hittin' the tropics, showin' off her adventurous side and sportin' bikinis like it's her day job ... Oh wait, it is her day job!

The 22-year-old -- who is celebrating her birthday later this week -- shared a series of snaps on social media captioned, "some girls just don't sit still ..."

And this blonde bombshell definitely ain't sittin' still! Goin' deep, Ponton dressed in her finest scuba-wear and gave a glimpse into life underwater with stingrays and other sea creatures.

And just above the surface, Olivia dove into a fresh plate of pasta while showing off her slim figure in a stringy bikini ... send noods!
