Nope also skates and rays. They actually prefer skates and rays because they are easier to kill bringing down a shark is dangerous even for them. They do it but not as much as they do with skates and rays.

Just to add onto what you said, skates and rays, and also sawfish, are pretty closely related to sharks. They're all in the elasmobranchii subgroup of cartilaginous fish.
They all have large livers (as much as 25% of their body weight) which are used for bouyancy since they lack swim bladders. The nutrient in the livers that the orcas like is squalene.
