Poison Jelly
Nearly invisible, the Box jellyfish is the most toxic of all jellyfish. With poison-lined tentacles, this strange creature injects a powerful mix of toxins into its victims that attack skin, heart and nervous system cells. Despite there being an anti-venom, many people don’t survive being attacked, but rather go into shock and end up drowning.
A Good Pet?
Despite some bad press, hyenas are not stupid, and lead highly coordinated group hunts to catch their prey. Fast and strong, with jaws that can break bones. Not normally known to attack humans – in true scavenger style hyenas will pounce on someone they feel is weak, injured or sick. With all that said, some hyenas have become successful pets.
