Frogs are famous for being accomplished leapers. In addition to their take-off, nearly all frogs control their trajectory through the air and the eventual landing. However, Essner et al. (2022) found that this is not true for the tiniest of frogs where size limitations have performance consequences. They demonstrate the small pumpkin toadlets (genus Brachycephalus) from Brazil do not control their posture after take-off, resulting in sometimes wildly uncontrolled landings. The authors hypothesize that the extremely tiny semicircular canals— the smallest yet recorded for an adult vertebrate— result in low sensitivity making it difficult for the frogs to sense their position as they move through the air.
