The New Scientist magazine (February 2022) documents research on captive orangutans, which reveals that orangutans can learn how to use stone tools as hammers and knives. However, they can’t make the tools.
Researchers at the University of Tubingen in Germany have been studying the behaviour of captive orangutans.
Alba Motes Rodrigo and her colleagues studied two male orangutans at the Kristiansand Zoo and Amusement Park in Norway. The Bornean Orangutans (Pongo pygmaeus) are mammals in the Hominidae family of apes.
The orangutans were given a sealed box of fruit (it was sealed with rope), a concrete hammer, and a lump of blunt rock.

Not all snakes are venomous, but scientists at the Chinese Academy of Sciences in Chengdu wanted to know more about venomous snakes.
The researchers studied venomous Sharp-Snouted Pit Vipers (Deinagkistrodon acutus). The New Scientist magazine (22 June 2021) reported the research results.
The aggressive Sharp-Snouted Pit Viper may be able to sense how much venom it has and it won’t attack if it doesn’t have enough venom (poison).
Previous research indicates that venomous animals, including spiders, scorpions, and snakes, use their venom frugally and carefully because they do not produce a lot of venom. However, previous research did not study the possibility of whether venomous snakes save their venom for specifc situations, such as self-defence.
