It's no secret that Australia is the home of some of the most dangerous animals in the world, but what exactly are the most menacing creatures of the land down under?
*** Not in exact order
Box Jellyfish
Almost invisible to the naked eye and extremley dangerous, this type of jellyfish is typically found in Northern Australia during the warmer months. With long tentacles that can stretch up to 6.4 feet ( 2m ) long, a sting from these Box jellies can immobilize your nerves and affect your breathing and movement. A substantial dose of venom can cause cardiac arrest and death within minutes.
Irukandji Jellyfish
They are both the smallest and one of the most venomous jellyfish in the world, Irukandji Jellyfish inhabit the northern waters of Australia. These jellies have an adult size of a cubic centimeter but have enough venom to kill. These Jellyfish produce a toxic venom that creates what called "The Irukandji Syndrome" which has tremendous effects on the human body including severe headache, backache, muscle pains, chest and abdominal pain, nausea and vomiting, sweating, anxiety, high blood pressure, tachycardia and pulmonary edema.
Crocodylus porosus (Salt water Croc)
Growing up to 6m (20ft) long, this is said to be the largest and most vicious croc of them all. A Salt Water Crocodile - otherwise known as a Saltie - can weigh up to 1 ton and is a carnivore (only eats meat), this Saltie is an extremley fast swimmer with sharp teeth and a huge jaw.
Blue Ringed Octopus
Known for its small blue rings, these octopuses are golf-ball sized with venom 1000 times more powerful than cyanide and enough to kill 26 humans within minutes. Blue-ringed octopuses produce a potent neurotoxin called tetrodotoxin that will cause muscle paralysis—including the muscles needed for humans to breathe, leading to respiratory arrest. There is no known antidote.
Sharks (The Big Three)
Classified as the 3 most dangerous types of Sharks, The Great White, Bull Shark and Tiger Shark are the most aggresive fish you'll find in the Ocean. Responsible for 140 known attacks in 2019, these Sharks have gained quite the reputation. The biggest great white sharks can reach up to 20 feet long and a 21-foot great white would produce a force of almost 4,000 pounds per square inch—that's four times stronger than a tiger or lion.
