There is a kind of bull ant living in eastern Australia. They are the largest ants in the world, and the length of worker ants can reach 3.7 cm. With their huge size, they are also very aggressive, and even bees are defeated by them. 1. morphological characteristics

bull ant, also known as red bulldog ant, is one of the bulldog ants. It is the largest ant species in the world, with an adult of about 1.5 cm to 3 cm and a worker of up to 3.7 cm in length. The head and chest of bull ants are usually reddish brown, and the back half of the abdomen is black. They have sharp serrated jaws and hard stings, which are their main weapons against their prey. 2. predation mode

Unlike ordinary ants, they have cooperative predation habits. Bull ants usually act alone when they prey. They will take the form of ambush, and when the prey passes by, they will jump behind each other like lightning, insert the thorn into each other's body and inject venom to kill them. However, adult bull ants can't eat solid food, but only suck the juice of trophies, and the bodies of their prey are moved back to their nests to feed their larvae. 3. temperament characteristics

bull ants are very violent and dare to fight against any enemy who gets in the way. They usually use powerful jaws and poisonous claws as attack weapons. Their venom is highly toxic, and it will cause severe pain after being stung, which will last for a day or two.
