Chironex

Most of you guys probably have never heard about what this is. A chironex is a type of jellyfish also named "The Box Jellyfish." The box jellyfish is the most dangerous animal in the world. Yes that means more dangerous than sharks and stingrays and a lionfish. It does not have a venemous bite or sharp teeth that would stab into you or a mouth at all. This jellyfish can kill up to 60 people in under 5 minutes with just 1 ounce of the venom. What makes his tentacles so dangerous you may ask? This jellyfish contains venom in each tentacles. The box jellyfish can have up to 60 tentacles which can grow up to 15 feet long. Some scientists have captured numerous of box jellyfish in a tank to study it. Each time they poured in alcohol in the tank they saw the stinging cells react to it which would cause it to release the venom. Later they concluded that if the stingers do not come in contact with human chemicals then the human will not be stung. Many of people are terrified to enter the water because of the box jellyfish, which has killed 100 people so far. People have started calling them the sucker punch jellyfish because you will never notice them coming until its already too late to react and it is extremely hard to ignore the pain and if you see someone stung by one it is important to immediately take them out of the water because they will most likely go into shock or wont be able to get out by themselves.

Kangaroos

A Kangaroos tail is very important to them for their daily activities. They need their tails to balance, so if you were to hold their tail down they wouldn't be able to balance or hop. Scientist call the Kangaroos tail "a third leg." Their tails are as long as their bodies and extremely strong. A kangaroos tail is so strong that it can put all its body weight on the tail and the tail would be able to supposrt the weight. When the kangaroo is grazing and foraging it uses three things, the two legs and the tail. It first uses all three of them and when they're ready they kick the two feet up together in the air and then swings them. Kangaroos do not have knee caps but the tibia bone of the Kangaroo has pads of shock-absorbing fibrous cartilage.
