Why can't these frogs jump?

Researchers used CT scans to figure out why these pumpkin toadlets are just no good at jumping. The inner ear system of these frogs is so tiny that they lose balance midair.

Fortunately their main survival tactic to avoid being eaten doesn’t involve high-speed getaways, but rather staying in one place and being as unappetizing or as inconspicuous as possible.

“They’re not jumping around a lot, and when they do, they’re probably not that worried about landing, because they’re doing it out of desperation,” study co-author Edward Stanley. “They get more benefits from being small than they lose from their inability to stick a landing.”
