A new study investigates how the world’s only singing lemur produces higher notes, describing the vocal behavior as more flexible than previously thought. Researchers report that the animal opens its mouth wider when it sings at higher pitches, suggesting a deliberate physical change tied to pitch control.

Both outlets frame the work as evidence that the lemur’s vocal technique resembles mechanisms used by trained opera singers, though the study does not claim the lemur performs opera. The comparison focuses on observable technique—particularly mouth shape and opening—rather than on musical training or performance style. The reports emphasize that the findings come from analysis of the lemur’s singing and the relationship between vocal effort and pitch.

Overall, the coverage highlights a single core result: the lemur’s higher notes are associated with a measurable change in how it vocalizes, offering researchers a clearer picture of the biology behind its distinctive “singing” ability.
