Toads have many sarcomas, which are ugly. However, for carnivores, ugliness will not affect the taste of toads. Although humans almost always avoid them like plague, other small and medium-sized animals like to prey on them, such as other bigger toads. Toad puffed up with air and propped himself up on four legs to make himself look bigger, so as to deter attackers. The weapon used by sugarcane toads in Australia to defend against enemies is poisonous. It is said that this is the main reason for their notoriety: large mammals that try to eat sugarcane toads will make their mouths full of toad venom. At first, they will eat tasteless and eventually die.
