Bats growl at each other like death metal singers 😠🦇🎶🥁

Bats have a tremendous vocal range of about 7 octaves, from 1 to 120 kilohertz! Most mammals have a range of 3 to 4 octaves, so this really is impressive. 

Higher frequency bat calls are used for echolocation, whereas lower frequency cries are how bats talk to each other. To make these lower pitched growling calls bats use structures in their throat, called ventricular folds, just like death metal and Tuvan throat singers do!

Cacti as far as the eye can see 🌵

The saguaro cactus is an iconic symbol of the American desert. It's the tallest cactus in North America, found in the Sonoran desert. The arms can take decades to form, as they grow their first side arms at 75 to 100 years old. They can live up to 200 years!

Large saguaros can weigh between 3000 to 4000kg and the vast majority of that weight comes from water stored in the stem.

Saguaros are a vital part of desert life, providing food and shelter for native people as well as homes and food for wildlife. Birds, like the Gila woodpecker, make their nests in the cactus. In early summer, the blooms provide nectar for bats. Mammals, reptiles and insects all enjoy the fruit. They are truly the lifeblood of the desert 🏜️
