Do monkeys fall out of trees?

Monkeys are primate mammals with a tail. They use their long tail to help them grip branches of trees. Their tail also helps them to maintain balance when they are climbing. It is called a prehensile tail. 

Monkeys also have wide hands and feet with sharp nails that also help them grip tree branches. To enable monkeys to swing among the treetops, they have long limbs.

The Saiga Antelope population is increasing in Kazakhstan

The Saiga Antelope (Saiga tatarica) is a critically endangered ungulate (hoofed) mammal. 

In 2015, there was a bacterial disease that killed many Saiga Antelopes. The population decreased by 60% making it a critically endangered species.

It is native to Russia and Kazakhstan. In winter, it migrates south to Uzbekistan and Turkmenistan. It used to be native to a wider area across Eurasia. It prefers semi-deserts, steppes, and grasslands, and it does not like steep and mountainous regions.

RESEARCH: Kangaroos can learn to ask humans for help

Research scientists have recently found that kangaroos in zoos and sanctuaries use body language to ask humans for help, much like horses and dogs do. The researchers think this suggests that wild animals can learn to engage in inter-species communication just by being around humans.

Previously, researchers thought that only domesticated animals had the ability to communicate with humans, said Alan McElligott at City University of Hong Kong.

Kangaroos in Australia have never been a domesticated animal. In Australia, there are about 50 million kangaroos that roam in groups, called mobs. But there are also thousands of kangaroos, and other marsupials such as wallabies and pademelons, that live in zoos, parks, and sanctuaries.

RESEARCH: Humans love big animals

All creatures great and small, but which ones are the best of all?

Humans seem to love big animals. Research scientists have found that people think that larger animals are more charismatic than smaller ones, with some exceptions.

Scientist Emilio Berti, previously from the Aarhus University in Denmark, and his colleagues, compiled information from 9 existing datasets on animal charisma. Some datasets included information from volunteers about their attitude to particular species of birds and mammals. Other datasets included information on the number of Wikipedia page views seen by readers for particular species of animals, and the number of images of species posted to Twitter and the photo-sharing site Flickr.

What is the difference between the California Sea Lion and the South African Fur Seal?

What is the difference between the California Sea Lion (Zalophus californianus) and the South African Fur Seal (Arctocephalus pusillus pusillus)?

The California Sea Lion and the South African Fur Seal are both marine (saltwater) mammals in the Pinnipedia clade and Otariidae family of sea lions and fur seals. 

The California Sea Lion and the South African Fur Seal have external ear flaps. Therefore, they are both otariids.

South African Fur Seal

The South African Fur Seal (Arctocephalus pusillus pusillus) is an aquatic marine (saltwater) mammal in the Pinnipedia clade and Otariidae family of sea lions and fur seals. It is an otariid or otary – a seal with external ear flaps – and a pinniped – fin footed. It is also known as the Cape Fur Seal or the Brown Fur Seal. 

The South African Fur Seal is grey-brown or black with a lighter underbelly, although the female is dark-brown. The male has a thick mane around its neck. It has a sleek, slender build with a thick neck, broad chest, broad shoulders, and a long, protruding face and nose. It has white whiskers on its chin called vibrissae. It has small external ears on the sides of its face.

Tasmanian Devils are reintroduced into Australia’s mainland

Eleven Tasmanian Devils (Sarcophilus harrisii) from the island state of Tasmania have been reintroduced into the mainland of Australia for the first time in 3,000 years.

The Tasmanian Devil is a marsupial mammal, an animal with a pouch. It once roamed the mainland of Australia and is now listed as endangered on the International Union for Conservation of Nature (IUCN) Red List. The Tasmanian Devil lived on the the mainland of Australia for 40,000 years until it died out due to the European introduction of foxes and cats in the 19th century that preyed on many native marsupial mammal species.

The Tasmanian Devil continued to live on the Tasmanian island in southern Australia, but many died over the past 20 years, since 2000, due to the Devil Facial Tumor Disease (DFTD), which is a cancer of the face. It is estimated that there are only 25,000 Tasmanian Devils left in Tasmania.

The longest whale dive ever recorded

Scientists have recorded the longest ever dive by a whale. The whale was a Cuvier’s Beaked Whale (Ziphius cavirostris). 

The time of the longest whale dive ever recorded was 3 hours and 42 minutes holding its breath. It broke the previous record in 2016 of 2 hours and 43 minutes. The human record for holding their breath underwater is 24 minutes. The human is floating motionless, but the whale is moving.
