The study looked at how temperature and salt levels affect the growth of Babylonia areolata embryos and larvae. They found that the best temperature for embryo development is between 23-31?℃, and the best salinity is between 28-38. For larvae, the best temperature is similar, but they need higher salinity levels of at least 30. If the temperature or salinity is outside these ranges, the embryos may not hatch properly and the larvae may not grow well. Overall, temperature has a bigger impact on development than salinity, and larvae are more sensitive to changes in salinity than embryos.
