| Abstract | The present paper describes the ultrastructural organisation of the epidermal glands in three pycnogonid species: Nymphon gracile, Achelia longipes, and Pycnogonum littorale. These glands are distributed over the whole body surface and lodged in cuticular holes. They are composed of at least five cells: two secretory cells, one enveloping cell, and two (or more) accessory cells. The presence of nerve extensions in contact with the enveloping cell stronly suggests that the glands are under nervous control. They may play a defensive role. |
