Why are these #frogs such clumsy jumpers?

Scientists have figured out why some miniaturized frogs from Brazil are such clumsy jumpers. A 2022 study published in Science Advances reveals that among adult vertebrates, members of the genus Brachycephalus have the smallest known semicircular canals – the part of the inner ear necessary for maintaining balance and spatial orientation.

The diminutive size of these canals results in low sensitivity to angular acceleration, preventing the frogs from controlling their posture as they prepare to land.

In other words they have reached to the biomechanical limits of said organ (inner ear labyrinth) by being so small.
