Two astonishing new discoveries have been made in the animal kingdom! Researchers in Scotland found that chimpanzees have a much deeper understanding of death than previously thought. When a fellow chimp is dying, they gather together to express grief. Another discovery is even more surprising: scientists have found that tadpoles emit high-frequency screams when threatened or under high stress.
Using underwater microphones, Argentine biologists have for the first time recorded tadpoles emitting high-frequency screams—though this behavior is only observed in tadpoles of the Ceratophrys genus. If the sound isn’t clear enough, listen to the larger tadpoles, nearly grown into frogs, whose calls are much louder.
Interestingly, these tadpoles don’t scream randomly. They only do so when bumped by other tadpoles or subjected to external forces, signaling they feel threatened. Since tadpoles sometimes eat those of other species, these screams serve a purpose. Researcher Natalia explains, "We hypothesize that when they make sounds underwater, it’s a warning: 'Don’t eat me, I’m one of you.'"
Scottish researchers have also made a new discovery. In the footage, three chimpanzees can be seen gathered around a dying companion, lingering for a long time and refusing to leave. Researcher Louise Locke said, "I was amazed that they all stayed by its side at the moment of death. Later, they touched the body, shook its shoulders, and moved its head."
Chimpanzees are known for their intelligence, and these zoo-dwelling chimps, who live together day and night, seem to display emotions similar to humans. After leaving the body of their companion, the chimps exhibited intense reactions—rolling around and thrashing violently. Zoologists say this is an expression of grief and anger. These rare recorded moments provide deeper insight into chimpanzee behavior.
