Sipunculus is a variant spelling of the Latin siphunculus ("little tube"),[2] a diminutive of sipho from Greek σίφων (síphōn, "tube, pipe").
Siphunculus was used for fossilized worm-shaped organisms like Siphunculus scaber by the Welsh naturalist Edward Lhuyd in 1699.[3] In the next century, the Swedish naturalist Carl Linnaeus used the scientific name Sipunculus nudus for a species of worms in his 1766 Systema Naturae.[4] In 1814, the French zoologist Constantine Samuel Rafinesque used the feminine form Sipuncula to distinguish the family including S. nudus;[5] this was later elevated to the Sipuncula class, the family being renamed Sipunculidae and the species reorganized into different genera.[6]
The genus has cosmopolitan distribution.[1]
