My son is 5 and I'm encouraging him to be curious and ask questions of the world around him. He asked if sharks fart and how does it smell? He feels that it would smell of fish and be disgusting.
He was also asking how anyone would know or be able to check. I don't know the answers and am teaching him how to research.

  • $\begingroup$ @Cameron Well done for encouraging your son. If I were you, I'd try to get him to think about how we sense the qualities that constitute a fart and what mechanisms create the fart. A fish may well fart but will we hear it? Will we smell it through the water? Linking back to the creation of the fart (production of gases in the intestinal tract), would we see a new effect like a bubbling in the water? $\endgroup$ – Jam Dec 11 '18 at 22:53

Yes,surprisingly enough sharks do fart when they gulp air from the surface of the water the air comes back through their body and comes out of their cloacas.
