Talk:Blowhole (anatomy)

Untitled
Any information on the evolutionary aspects of the blowhole? Any other species has or had it? Enlil Ninlil 00:49, 6 June 2007 (UTC)
 * I know the evolution is well documented, so I'll look that up again some time and add it. BabyNuke 17:59, 6 June 2007 (UTC)

In mamals, the trachea is "in front" (or below) the spine. Therefore, I'd like to know if the trachea passes to the left of the spine, to the right of it, or maybe on both sides?Pburto 06:50, 21 September 2007 (UTC)
 * It doesn't "pass" the spine at all, actually. The trachea passes through the skull still in front of the brain to connect to the blowhole, which is located roughly on top of the head. BabyNuke 11:45, 21 September 2007 (UTC)

I think it would be great to include this amazing image showing fossil evidence for the evolution of blowholes:



The only problem is that it doesn't name the species each skull is from. But it's still a great image. Tredanse (talk) 13:28, 5 June 2008 (UTC)

Questions: Why two blow holes? Does one exhale while the other inhale (as in reptiles, birds, amphibians that have separate paths for inhale and exhale) or are the two passages immediately connected inside the animal? — Preceding unsigned comment added by 69.244.42.229 (talk) 18:18, 11 July 2012 (UTC)

Reference?
How about some references for the artilce? Leading books that cover blowholes. Careful readers will wonder what these are. --Firefly322 (talk) 02:39, 5 July 2008 (UTC) Not a reason to delete or AfD. Just a nice thing to have. --Firefly322 (talk) 12:58, 5 July 2008 (UTC)
 * Hello, I added in a few sentences discussing more in depth as to how the air sacs work in whales when they dive underwater. I cited my addition with a journal article discussing this process. I thought it would be a good addition to that section to give the reader a little more knowledge as to how the muscles of the blowhole work. Lexiehiggins (talk) 02:35, 25 February 2017 (UTC)

"evolved via gradual movement of the nostrils to the top of the head" Now THAT is funny!! Good one!75.73.118.185 (talk) 00:10, 12 February 2021 (UTC)
