Snake antivenom is a human life-saver… but comes from horses!
- ‘Snake antivenom’ is also known as ‘snake antivenin’ and ‘snake antivenene’.
- Snake antivenom is typically a liquid substance that contains antibodies that help destroy snake venom.
- Snake antivenom is created by injecting the snake’s venom, which has been ‘milked’, into an animal, such as a horse, which will create antibodies that are later extracted.
- Snake antivenom should always be given to a snake-bite victim if the snake is poisonous and the venom has spread through the victim’s body.
- Allergic reactions can occur after a patient has been given snake antivenom, but it only occurs in 10% of patients.

- Snake antivenom should be administered when symptoms such as headaches, pains, loss of consciousness, paralysis and nausea occur, and a snakebite may have occurred.
- Snake antivenom should not be frozen but instead refrigerated, and usually has a storage life of three years.
- Snake antivenom was invented in 1894 by Léon Charles Albert Calmette, a French immunologist.
- Snake antivenom can cost up to $1600 per vial, depending on the type, while a single person with a snake bite can use as many as 20 to 25 vials.
- Snake antivenom can take years to make, and take more years for approval by the World Health Organization (WHO) before the product is usable.

It is Saltie the Saltwater Crocodile!
- Saltwater crocodiles are the world’s largest reptiles, growing an average of 3 to 5 meters (10 to 17 feet) in length, depending on the gender, and can grow up to 7 meters (23 feet) long.
- ‘Saltwater crocodiles’ are also known as ‘salties’, ‘estuarine’ and ‘Indo-Pacific crocodiles’, and their scientific name is crocodylus porosus.
- Saltwater crocodiles generally weigh between 400 to 1000 kilograms (880 to 2200 pounds) but they can be as heavy as 2000 kilograms (4400 pounds).
- Saltwater crocodiles are typically found in mangrove swamps, deltas, lagoons, rivers, and estuaries, and can also be found swimming in the ocean, which they sometimes use to travel long distances during different seasons.
- Saltwater crocodiles are native to South-east Asia, including India, and Australia.
- Saltwater crocodiles have vibration-sensing teeth, and their diet generally consists of fish, sharks, reptiles, birds, crustaceans and mammals although they cannot swallow their prey underwater.
- A saltwater crocodile’s bite is the strongest of all non-extinct animals, as its teeth are designed to hold its prey and prevent it from escaping.
- Saltwater crocodiles are the most dangerous crocodile, although attacks are not frequent, however there are usually a couple of human fatalities each year.
- Saltwater crocodiles can lay up to 60 eggs at a time and baby salties are pale yellow in colour with black patterns, while the adults are generally murky green or greenish-black in colour with a pale yellow underbelly.
- In 1971, 95% of the original Australian saltwater crocodile population had been hunted, commonly for its skin, however the species is now protected in Australia, and the population has recovered.
