Which mammal has no vocal cords?

Giraffe✅

The giraffe, the world’s tallest land animal, is the mammal associated with having no vocal cords. For centuries, this creature was considered to be almost entirely silent, leading to the assumption that it was essentially mute. Early observers believed that the giraffe simply could not produce sound because of its unique anatomy, despite anecdotal reports of occasional moans, snorts, or grunts. Recent scientific investigation, however, has revealed that the giraffe is not silent, but rather employs a communication strategy that is difficult for human ears to detect.
