African Elephant
Another creature that made the list because of its size is this one. The African elephant may appear to be a harmless creature, but that does not mean it is not dangerous. The old and young male elephants have the most difficult time. Be careful around them because their 12,000-pound weight can crush you.
Portuguese Man O’ War
Do you know what the Portuguese Man O’ War is? It’s a siphonophore, which means it’s made up of several colonies that work together to stay alive. They are truly amazing creatures to observe. Some of them have tentacles that can reach 165 feet in length! Whoa.
