Porcupine Puffer Fish: when puffer fish are forced to puff up, they induce a process physiologically similar to having a heart attack. In some cases, the puffing is hard enough on their systems to be fatal.
The redback spider (Latrodectus hasseltii) is a dangerous spider endemic to Australia. It is a member of the genus Latrodectus, the widow spiders, which are found throughout the world. The female is easily recognisable by her black body with a prominent red stripe on the upper side (i.e. the back) of her abdomen.
