Abstract: Spinning organs of Heteropoda venaatoria, a "hunter" spider, were histologically and anatomically studied in order to clarify the difference in spinning organs between the "snarer" ane "hunter" about which little information has been offered. Followings are the results obtained in the present study. In the adult female of H. venatoria, two ampullaceal glands open through two spigots of the C-type and pifiform glands through about 180 spools of the E-type on each anterior spinneret; two tubuliform glands open through two spigots and aciniform glands through about 36 spools of the F-type on each middle spinneret; and aciniform glands open through about 43 spools on each posterior spinneret. In the adult male of the same species, an ambullaceal gland opens through a spigot of the C-type and piriform glands through about 131 spools of the E-type on each anterior spinneret; an ampullaceal gland through a spigot, and aciniform glands through about 43 spools of the F-type on each middle spinneret; and aciniform glands open through about 55 spools on each posterior spinneret. The difference in spinning organ was discussed between adults and sub-adults of H. venatoria, and between the "hunter" and "snarer" of spiders.
