(via TYWKIWDBI (“Tai-Wiki-Widbee”): Tarsiers communicate using ultrasound) Marissa Ramsier of Humboldt State University in California and her colleagues were puzzled to sometimes hear no sound when Philippine tarsiers (Tarsius syrichta) opened their mouths as if to call. Placing 35 wild animals in front of an ultrasound detector revealed that what they assumed to be yawns were high-pitched screams beyond the range of human hearing…Whales, dolphins, domestic cats and some bats and rodents are the only other mammals known to communicate in this way.
