A team of researchers affiliated with several institutions in the U.S. and Brazil has found evidence that pumpkin toadlets (Brachycephalus) have poor jumping skills because their inner ear canals are too small. In their paper published in the journal Science Advances, the group describes their study of the inner-ear anatomy of nearly 150 frogs and toads. The researchers believe that the inner ear canals of pumpkin toadlets are too small to allow them to land gracefully.
