Frogs occupy many different microhabitats, from underground burrows to the tops of the tallest rainforest trees. In a recent article, Citadini et al. (2018) wanted to better understand how limbs and locomotion varied among frogs that occupy different microhabitats. The authors examined limb evolution and quantified maximum jumping distance for 64 frog species from Brazil and Australia. They found that torrent, arboreal, and semi- aquatic frogs tended to have longer hindlimbs and jumped farther whereas fossorial and terrestrial species often had shorter hindlimbs and jumped less far. Citadini et al. support the overall hypothesis that limb evolution plays an important role in allowing frogs to occupy such a large range of microhabitats.
