How Fish Smell and Breathe

I've completed part of my term project, focusing on the "nostrils," or more properly, nares in fish. I based my findings primarily on Koi anatomy. Species vary. In species with barbel (the hair-like appendage from sides of mouth, like this koi) are also used in the detection of scent / food as well.

Adding longer cilia. Needs some trimming.
Just completed this morning... the model is still in the process of drying.

Model based on Roles of the olfactory epithelium, glomerulus, and mitral cells-olfactory nerve in smell.
