With only one male northern white rhino left in this planet, efforts to eradicate poaching had been strengthened. To discourage illegal hunters, anti-poaching groups had placed cameras on the horns of the critically endangered species while researchers had developed lab-grown horns as an alternative.

Recently, a team in Kenya recruited a new member to stop hunters from savagely killing rhinos for their horns. Diego, an anti-poaching dog from the Ol Pejeta Conservatory in Kenya, is certainly a rhino’s best friend. Reaching a speed of up to 40mph, Diego got what it takes to protect the last male northern white rhino in the world.

Thanks to Diego, the sanctuary has not lost a rhino in over a year.

A study on howler monkeys highlights something that may be true for a majority of male animals — including humans.

In the course of his study on howler monkeys, Dr. Jacob Dunn — lead researcher of the University of Cambridge’s Division of Biological Anthropology — noted that the males with the loudest mating calls often had smaller testes.

Native to Central and South America, howler monkeys are tagged as one of the loudest animals in the planet. The male monkeys are known for their deep roars, which reach up to 128 to 140 decibels. They use the sound to declare their supremacy, which they hope would dissuade rivals and attract females at the same time.

Unlike domestic pets and other animals, bats are not really that appealing. People usually think of them as creatures who lurk in the night and are usually represented as dark beings that turn into vampires in movies. We don't usually see them as adorable, cuddly creatures. However, in this video, you will be able to change the way you think about bats. You will realize that mothers care about their babies no matter what species they are.

The ACRES Wildlife rescue team found a baby bat that was stranded for almost two hours. They laid it on the ground as they waited for its mother to come. It is actually amazing to see that the bat pup was continuously crying for help sending a signal to its mother while the mother bat was flying around to locate her baby. And as expected, after two minutes of waiting, the mother bat finally found her baby and they are once again reunited. The rescue team was happy to see them together again and the touching reunion was all caught on video.

Let's watch the heartwarming mother and baby bat reunion here:
