Talk:Blowhole (biology)

From Wikipedia, the free encyclopedia

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)
