Yes, Squids have gills. They need them to breathe underwater. There's different kinds of squids and therefore different kinds of gills that they have but generally they have a total of 4 gills, 2 on each side. On a sidenote to the previous answer: Squids are NOT fish.
Clams have a couple sets of gills. They have one on each side of their feet and two in their shell linings.
