 Male spiders spin a silken platform (sperm web) on the ground onto which they release semen from glands in their opisthosoma.Then they insert their pedipalps into the semen, absorb the semen into the pedipalps, and later insert the pedipalps (one at a time) into the reproductive organ of the female, which is located in her abdomen.The terminal segments of the pedipalps of male tarantulas are moderately larger in circumference than those of a female tarantula.
