1. Electroreception -Electric systems: reception vs EOD -Electroreception: prevalence, types, functions -My question: How has electroreception evolved across organisms? -Why is this interesting? -What methods did scientists use for studies? What did I find? -What does this mean/what is the importance? BSCI338C, Dr. Karen Carleton Fall 2009, Univ. of MD Final Project Libby Tsytsikova
