This publication explores the behavioral influence of pharmaceutical pollution on a species of estuarine crab. Fluoxetine is a commonly prescribed, fairly effective anti-depressant and anti-anxiety medication. Its effects are well-documented in humans, but little research has been conducted to determine how concentrations of fluoxetine within aquatic habitats alter the survivorship and behavioral patterns of the species living there. The researchers that put forth the data at the source of this project expose the Oregon shore crab to varying levels of fluoxetine and record their behaviors. The research itself consists of two different portions: intraspecific interactions and interspecific interactions. As a result of this experiment, the crabs exposed to 30 ng/L of fluoxetine were found to be less risk-averse, leading them to get into more fights amongst their own species and become more likely to be killed by predators.
