Abstract: | Summary The effects have been studied of different salinities on the early stages of development of the Turbellarian Polyclad Stylochus mediterraneus Galleni. Optimal salinities are about 30%o. Variation away from this value increases the incidence of unhatched embryos, even if development is not greatly altered. On the contrary, at the highest tested salinities (50%o; 60%o) and the lowest (18%o), embryos are affected by great alterations in their morphology. |
