It is possible that you have two different conditions. For example, it sounds like you have a long standing history of your jaw popping when you chew, which is definitely not a symptoms of an ear problem! At the same time, your doctor recently diagnosed you with a likely ear infection. This can be complicated, because an ear infection can cause pain that radiates down into the jaw area. Typically this pain will get better as the infection goes away. What I would suggest, therefore, is that you go back to see your primary care doctor to make sure the ear infection is getting better.
Other ancient bivalves appear to have a double set of gills. The second sets of gills actually arise from a folding of the single gill. This is the case in the Filibranchia and Eulamellibranchia, where the gills have also taken over the function of obtaining food.ther ancient bivalves appear to have a double set of gills.

They are crustaceans just like crabs, lobsters, shrimp, sea monkeys and sowbugs.Their gills are part of the biramous appendages on the underside of their abdomen (the same as the tail of a lobster).These appendages have two parts, the paddle-like swimming legs, and the leaf shaped gills.hey are crustaceans just like crabs, lobsters, shrimp, sea monkeys and sowbugs.
