Toxic and deadly African snakes

Some of the deadly African snakes at Snake Park in Nairobi, Kenya, include the Black Necked Spitting Cobra, the Black Mamba, the Green Mamba, and the Puff Adder.

The Black Necked Spitting Cobra (Naja nigricollis) is glossy black and grows up to 2.7 metres (9 feet) long. It lives along the coast and in semi-desert lands. It eats toads, chicken eggs, lizards, and other snakes. It lays from 8-20 eggs per clutch. It is venomous – its venom is cytotoxic (poisonous to cells) and neurotoxic (poisonous to the nervous system).

The Black Mamba (Dendroaspis polylepis) is a long slender olive, brown, or grey snake, growing up to 3.2 metres (10.5 feet) long. It likes high bushlands at about 1600 metres (5249 feet) above sea level. It is a very fast moving snake that can climb trees. It is active during the day (diurnal). It eats mice, rats, bats, elephant shrews, squirrels, birds, and other snakes. It lays 6-17 eggs per clutch. The Black Mamba is both neurotoxic and cardiotoxic (affecting the heart), causing paralysis.

The Green Mamba (Dendroaspis angusticeps) is a large thin bright green snake, growing up to 2.3 metres (7.5 feet) long. It lives in coastal bush, moist savanna, and evergreen hill forests. It is a fast moving tree snake, active during the day. It eats birds, rodents, and bats. It lays up to 17 eggs per clutch. The Green Mamba has a potent neurotoxic venom.

The Puff Adder (Bitis arientans) is Africa’s most dangerous snake – producing cytotoxic venom. It is a brown or grey viper with V-shaped light rings and a broad triangular head, growing up to 1.9 metres (6 feet). It lives in many habitats from sea level to about 2400 metres (7874 feet) above sea level. It is nocturnal (active at night), but sometimes active during rainy days. It is slow moving, usually moving in a straight line. The Puff Adder eats small mammals. It gives birth to live young.

Apes go to the movies - and remember the scenes

Apes remember major events in movies, even after a single viewing. That’s the findings of primate research in Japan (New Scientist, September 17, 2015). Researchers at the Kyoto University in Japan conducted experiments with two species of apes – chimpanzees and bonobo primates – to test their memory and recall. Instead of using food to test memory, they used films. The researchers made two short movies to show to the apes. Fumihiro Kano and his colleague, Satoshi Hirata, starred in the films with another person dressed as an ape. They wanted to have strong dramatic scenes to see if the apes remembered them. In the first 30-second movie the character ape bursts through a door on the right hand side (there is also a door on the left hand side) and attacks the two researchers (characters) 18 seconds after the start. After 24 seconds a human character choses one of two weapons next to each other and launched a revenge attack on the ape. In the second 30-second movie t...

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.
