Contamination of the aquatic environment with endocrine disrupting compounds (EDCs) remains an important and emerging issue.  EDC exposure concentrations that are typically needed to affect biological changes in fishes and other biota are relatively low, and concentrations observed in certain waterways appear sufficient to be associated with intersex in some fishes.

List three (3) anatomical features/structures of fish where their form can tell you something about their function, i.e., you can judge aspects of how the fish interacts with its environment, swims, diet, etc.  For each anatomical feature/structure you list, in just a few words describe how it helps your fish “be that fish” and occupy its niche, and provide an example of the kind of fish that has the feature(s)/structure(s) you describe.     

Countershading is a form of dark coloration used by some fishes used to attract light and heat their cold-blooded (poikilothermic) bodies in environments that can fluctuate in temperature.

Point-source and non-point sources of nutrient loading are associated with accelerated eutrophication of water bodies, habitat depletion and altered species diversity.

A family visiting a Florida beach returned to their hotel room after an afternoon on the beach in the sun. Both children and one of the parents were coughing intermittently, had itchy runny eyes, and a drippy nose.  These symptoms are consistent with exposure to beach aerosols containing one of several Vibrio species.

Vibrio vulnificus can be associated with both seafood poisoning as well as wound infection.

Freshwater fishes osmoregulate, in part, by  excreting large volumes of dilute urine.
