Despite this concern, there remains some scepticism about the reproducibility and reliability of research done to predict the future climate change impacts on marine organisms. Here we present meta-analyses of over two decades of research on the climate change impacts on an ecologically and economically valuable Sydney rock oyster, <em>Saccostrea glomerata</em>. We confirm with high confidence that ocean acidification has a significant impact on mortality and size of <em>S. glomerata,</em> that ocean warming has a significant impact on mortality, but not size, and transgenerational exposure has positive benefits to offspring. These meta-analyses reveal impacts of climate change on an ecologically and economically significant oyster species and recommends solutions for experimental designs to ensure sustainability of this iconic oyster. </div>

Fig. 4 in Predation of Oysters Using an Autonomic Pharynx in the Oyster Leech sp. (Polycladida: Stylochidae).
Fig. 4. The three predatory processes for Cryptostylochus sp. on Portuguese oysters (Magallana angulata). A, Attack period: flatworms extend their pharynx into the oyster from the shell opening for 4 to 8 hours and some autonomic pharynges are formed. B, Invasion period: the stylochid flatworms crawl into the shell after the oyster cannot resist and the oyster gradually loses its ability to close its shell. C, Ingestion period: the flatworm wraps the entire oyster flesh and separates it from the shell. f, flatworm; o, oyster; p, protruding pharynx.

Fig. 2. Illustration of the collection of autonomic pharynges from Cryptostylochus sp. The flatworm is flipped over with its ventral surface facing upward. The highly ruffled pharynx is everted under stimulation by pressing the ventral surface with a paintbrush. The pharynx extends and spontaneously breaks into pieces of autonomic pharynges, which are collected by tweezers.
