Communication occurs through different modalities and for varying functions in marine mammals. Identify the four main modalities of communication and explain the function of each of these modes of communication for different marine mammal taxa (i.e. different marine mammals use the same mode of communication for similar and/or different reasons….explain how marine mammals use that mode of communication in similar and differing fashions).    Bonus (1pt): What factors, such as specific situations and/or environmental conditions might influence an animal’s choice in using one mode of communication versus another mode of communication?  

Take a moment to reflect on the information presented in Modules 4-6 (Thermoregulation, Diving Physiology, and Sensory Biology & Acoustics). For each module, identify and describe a minimum of one concept that you feel was strongly examined throughout the module and one concept that you feel was weakly examined and that you did not understand well by the end of each module.    To provide additional clarity, an example may be:   Thermoregulation (Module 4) One concept that you understood well from this module was x-concept and you felt it was really well described and thus you provide a succinct, yet insightful description of this concept and what you learned about it with specific examples to either a marine mammal species or taxa or to multiple marine mammal species/taxa. One concept that you did not understand well from this module was y-concept. You provide an explanation as to why you do not understand this concept that well or what factors have hindered your understanding of this concept. You also identify and examine additional aspects you feel would benefit this module and your overall understanding of the module topic. You are welcome to examine the topic and write about what you believe to be your knowledge and identify any shortcomings and/or gaps in your knowledge currently.    Although this is essentially a free question, you should provide sufficient information without repeating any answers for the previous quiz questions. Simply completing the question does not guarantee full points. Points are determined by the quality of your responses.
