[1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.

Non-reproductive cannibalism: Some spiders, such as Pholcus phalangioides, will prey on their own kind when food is scarce. [18]

Tarantulas use their pedipalps to help groom themselves, especially after a meal. During reproduction, males use their pedipalps as external reproductive organs. They develop emboli and palpal bulbs on the ends of each palp. [4] Tarantulas have 8 legs and each foot ends with a cluster of bristles called scopulae and a pair of tarsal claws ...
