That was my first thought but can dolphins breathe out of their mouths?

*Searching say no. Can I say duckduckgoing? Ducking? Ducking says no. Separate breathing and feeding tubes. We should do that.

**More ducking says "Until recently it was thought that dolphins could not breathe through their mouths in the same way as people can, only through their blowholes. However, in 2016 scientists discovered a New Zealand dolphin with a damaged blowhole who had learnt to breathe through his or her mouth."
