Tigers are often looked as being one of the most beautiful yet ferocious animals and perhaps this is a sole driving factor that makes them even more interesting creatures. But sadly, they have come to a verge of being categorized as endangered, thanks to the human sloppiness and prudence. As a wildlife lover with keen interest on large cats, I enjoy visiting wildlife sanctuaries but the question remains, how well do I or we know about this exotic animal? Spoiler alert - you would be knowing some of the facts already but what the hell! You probably knew this that Royal Bengal Tigers are the largest amongst other wild cats but did you also know that the male Tigers weigh up to kilograms. Kidding, you cannot have a pet tiger, it illegal!
Jungle Animal Sounds
Tiger Roar – PoC
Not all cats roar which is probably a good thing for those of us who own housecats , but those that do fascinate us with their mysterious and frightening sounds. A group of biologists and speech scientists studied how lions and tigers roar by examining and testing tissue from the larynges of three lions and three tigers from the Henry Doorly Zoo in Omaha that had been euthanized because they were old and sick. The researchers were particularly interested in the vocal fold tissues, soft connective tissues made of collagen, elastin, a lubricant and fat. Vocal folds are just another name for vocal cords, and they are a bit different in lions and tigers than in other species. But in lions and tigers, the protrusions are flat and shaped like a square, courtesy of the fat deep within the vocal fold ligament.
A tiger's intimidating roar has the power to paralyze the animal that hears it and that even includes experienced human trainers. Bioacoustics is the study of the frequency or pitch, loudness, and duration of animal sounds to learn about an animal's behavior. At the meeting, von Muggenthaler discussed her work analyzing the frequency of tiger sounds to better understand the part of a tiger's roar that we can feel, but can't hear. The lower the frequency, the farther the distance the sound can travel.
Lions and tigers may have deep, knee-quaking roars, but the sound quality is not so different from the grating cry of a newborn human. Now, a new study finds the specially shaped vocal cords and a layer of soft fat allow big cats to roar loudly with little effort. There's a purpose to that — it's attention-getting.
