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.     

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.

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.

Provide an example of a chemical, biological and physical stressor that can impact the well-being of sustainable, healthy oyster reef. This question is asking for a list of three stressors (single words or phrases).

Fish can have taste buds over many different parts of their body – one of many mechanisms for fish to “know their environment.”  Fish also have ears.

Ciguatera poisoning is the most commonly reported marine toxin disease reported worldwide.  It is caused by ingestion of higher trophic-level fish, like barracuda, that have high concentrations of toxins from the dinoflagellate Gambierdiscus toxicus that have accumulated up the food chain .
