The influence of copper on embryonic development and hatching ofSepia officinalis was investigated. Copper exerts a profound effect on both hatching stage and time-to-hatching. At high copper concentrations (50–200 ppb Cu2+), the embryos hatch earlier than the controls but have a lower survival potential. No external morphological malformations were found. Whereas copper does not accumulate in the embryo or in the vitellus, it is absorbed by the envelope and/or the chorion. |
