This frog's angry roar ensures that all of us will be scared.

Make sure this is the most "scary" sound you've ever heard in the world.

Animals in a dangerous natural world have different instincts to deal with a threatened situation. As the growl grinned at the tiger's fangs, the sound of "fire-breathing" of snakes, or the ability of camouflage camouflage.

They make so "horrible" sounds that you won't be able to imagine.

For frogs, they choose to react as "screaming" , emitting characteristic noises, just as the tiger or lion still makes to threaten the enemy.

And as a member of the frog family, the Desert Rain Frog also has a similar defense. They make so "horrible" sounds that you won't be able to imagine.

How is their cry? Luckily, photographer Dean Boshoff has been "brave" to approach, saving this "scary" sound. If you're brave enough, listen to it, make sure you're surprised.

Interesting? This "creepy" frog frog is native to Namibia and South Africa. They spend most of the day hiding deep in the sand to cool and moisturize the body. Only when they are hungry can they find their way out of hiding to find bait (usually small insects).

This is one of the frogs in a critical state, listed in the IUCN Red List. The reason is because people have been continuously destroying their habitats by opening roads and exploiting diamonds.
