Summary
The distal half of the posterior tentacle of adult Helix aspersa and Cryptomphallus aspersa was removed and the proximal half was studied with light and electron microscopy after different intervals. The tentacle itself does not regenerate, but the receptor organs at the distal end of the normal tentacle differentiate at the level of the section. The newly formed eye is smaller than the control; however, its components and subcellular characteristics resemble those of the normal eye.
