Lasiodora parahybana pairing
Lasiodora parahybana, the Brazilian salmon pink bird-eating tarantula, also simply known as the salmon pink or LP, is a tarantula from north-eastern Brazil and considered to be the third largest tarantula in the world (behind Theraphosa blondi and Theraphosa apophysis; however, the largest spider in terms of leg-span is the giant huntsman spider).
In this video you will see a Psalmopoeus irminia (Venezuelan Suntiger) tarantula pairing, the male is grey and circling the female for a good position to make an insert using his pedipalps. The differences between male and female Tarantulas (known as sexual dimorphism) depend on the species. Sometimes, the differences in male spider characteristics and female spider characteristics are obvious. In other cases, a microscope may be required.
