These are some of the African animals known to prey often on snakes, both venomous and non-venomous:
Crocodile: Crocodiles are found in African rivers. They have numerous sharp teeth for biting and tearing prey and have strong jaws for holding on to prey and killing them. Their body is covered in armor-like skin making them impermeable to snake bites. Crocodiles are unforgiving of snakes when they cross their path. Crocodiles may swallow snakes whole, or crunch them with their long sharp teeth.
Mongoose: Mongooses are small carnivores that prey on a wide range of prey such as birds, insects, small mammals, snakes – both venomous and non-venomous – and other reptiles. They are well-known snake hunters wherever they are found.
Secretary bird: The secretary bird has long legs and speed. Their long legs give them an advantage over snakes, whether venomous or non-venomous. They stomp snakes to their death and swallow them whole. They are normally found prowling on the open grass for snakes and other small reptiles. They also have the nickname killer queens.
Brown Snake Eagle: The brown snake eagle is common in many African regions. Eagles as they are, they have sharp beaks and talons for killing prey of all kinds including snakes, both venomous and non-venomous. Aside from their beaks and talons, they have good eyesight and can spot snakes far away and attack them. Since these birds have the speed, boldness, sharp beaks, and talons to do the kill, the snakes which are attacked by them have very little chance of getting away.
Honey Badger: the Honey Badgers are carnivorous mammals a little bigger than a house cat. They are cousins to the wolverine which is found in North America, Europe, and Asia. However, honey badgers are found in Africa – on the African planes – and Southwest Asia.
They are vicious hunters who make do with any prey that gets in their way. On many occasions, they are found fighting with snakes, venomous and non-venomous, big and small. Normally, a honey badger-snake fight goes in favor of the honey badger and they kill and eat the snake. It is believed that they have some amount of immunity to snake venom.
