Believe it or of by body count of dead.... It is the Mosquito It's ability to transfer/spread diseases across countries and around the world makes it have the largest kill rate of them all with malaria being the most deadly. Approximately 2.3 % of all deaths on the planet are caused by malaria
it is man we are part of the kingdom animalia so we are animals and since we kill almost anything including other humans we are the most dangerous so no it is not the mosqouito we are the killers we make antibiotics and vaccines the bacteria or virus evolves and we get malaria or herpes or all the other diseases oh and by the way the malaria kills not the mosquito and malaria is part of a different kingdom
Us we r killing other animals for stupid money we r tearing down other animals homes we r poluting r planet and there r about 1million more answers but ya :( ps I hate man soooo much I no I'm a human but really war money? Fu****g stupid!
I've heard of boxed jelly fish like someone else said and there is a blue ringed thing in same area looked like a star fish.. Not sure exactly what it is saw it on a show when it was talking about deadliest animals. Lol some snakes are really bad though too
