Every week, we share an interesting fact from the natural world on our social media. In July, we had a collection of animals that can sleep standing up; dolphins who call each other by unique names; Ecuador discovered an extinct tortoise species and horses are using facial impressions to communicate.

Animals that Can Sleep Standing Up

We have collected a few animals that can sleep standing up. There are a few more wich we didn’t include in our list.

Giant Tortoise Found Know to Be Extinct for 112 Years

Ecuador confirmed a giant tortoise they found two years ago belongs to the Chelonoidis phantasticus species. This is extremely good news because they believed those turtles were extinct.

Dolphins Call Each Other by Name

They use a unique whistle to identify each other. A team from the University of St Andrews in Scotland found that when the animals hear their own call played back to them, they respond.

Do you know any other animals that call each other by name?

Horses Use Facial Expressions to Communicate

Our equine friends use seventeen facial expressions to communicate. This is fascinating because that is ten fewer than humans but four more than chimpanzees.

Do you know other animals which can use facial expressions too?
