This may come across as a sort or rant, but that is not the intention, just observation and curiosity.

I've been working on M&A for a while now trying to prepare it for a 2015 publishing date. My main character is Tigershark - a shark anthro. There was a lot of thought put into Tigershark's design over the years, from the minor aesthetic choices to ones that are medically and physiologically possible for such a mutation to be successful.

I'm very much into design choices and physical characteristics making some sort of scientific sense. And some times I see things that make me go: "hmmm, how could that logically work?" Such is the case with the placement of gills on an anthro character.

I have seen many gilled anthros in both art and film and TV and one of the design choices I could never quite fathom was placement of gills on the chest.

For a humanoid who still has lung tissue a chest gill design makes little to no sense to me. It would mean that water would need to be drawn into the lungs in order for the water to be seined through the gill tissue to extract oxygen. With the way lungs work, filling the alveoli with water would only cause problems. (IE Pneumonia)

Fish have evolved where the gills are just aft of the head and connected directly to the mouth. This allows for a bellows effect which draws water into the mouth and out the gills, passing water over the structures that pull oxygen directly from the water.

Logically - my head tells me the same should be true for an antrho with gills as well. I believe they should have placement either aft of the jawline or on the neck above the location of the epiglottis.

This would allow for the adaptation of the epiglottis to close off the lungs while gills are in use and not flood the lungs with water.

It just seems to me that a chest gilled anthro would have major health issues (unless the lungs weren't present, in which case it really wouldn't matter a whole lot - aside that it wouldn't be an efficient gas seining system because of distance between intake and outflow.) and might not survive for any real length of time.

That's my two cents worth - thanks for reading... moving on with my day.

yes yes yes I agree completely. Many people are so caught up with how cool something might look that they lose sight of how implausible it becomes
