*[129 - 2023-05-18 - Aventis III - Epidaurus - Greece](129%20-%202023-05-18%20-%20Aventis%20III%20-%20Epidaurus%20-%20Greece.md) - This picture was described in [Sabella spallanzanii - Mediterranean fanworm](Sabella%20spallanzanii%20-%20Mediterranean%20fanworm.md) because of the worms tube, but it's interesting to see closer H. sanctori's tegument. We can see that it have some little spines, outing the white spotted holes.*
