The option that applies only to embryos rather than adults is:
**gill slits that turn into gills**
In the embryonic stage of both fish and reptiles, gill slits are present, but in reptiles, these structures do not develop into functional gills as they do in fish. In adults, fish have gills, while reptiles do not.
