Bird-eating spider The heaviest spider in the world

Bird-eating spiders, namely bird spiders in North America and babas in Africa, are all big guys of the bird-catching spider family. They are comparable in size to the largest terrestrial invertebrates such as the Goliath centipede, the giant beetle, and the king scorpion. The giant bird spider in northern South America, the male appendage can reach a length of 26 centimeters, but the weight does not exceed 85 grams.

Bird spiders inhabit forests, but some are found in arid and barren areas, such as Mexico and the southwestern United States, where there are many species adapted to desert life. The typical body color of a bird spider is black or brown, but some of them are brightly colored.

Despite their terrible appearance, many species have a gentle disposition and only attack humans when provoked. But some others, especially the African species, are hot-tempered and aggressive. After many bird spiders bite people, the wound will be very painful, but basically there is no more harm. When attacking, the bird spider will lift the front body, the appendages will also be lifted, and then forcefully knock into the body of the prey into the large poisonous fangs. Such a force makes Venom seem less important. When stimulated, the New World's bird spiders can also throw clumps of cilia from their abdomen. This cilia can be very dangerous if rubbed into the eye, because these cilia have tiny barbs on them that make it impossible to remove them.

The name "bird-eating spiders" is slightly misleading, as bird spiders rarely catch birds, and their diets are more of small reptiles, amphibians, beetles, moths, grasshoppers, and other spiders. Some species are said to prey on small snakes. Bird spiders have many enemies, and mammals dig them out of their burrows; birds, reptiles, amphibians prey on juvenile spiders= they also receive the attention of certain wasps who paralyze the spider with their spines, then drag them into the burrow and seal the burrow after laying eggs on it. After hatching, the larvae feed on spiders that are still alive.
