General approach
• Focus on the big picture: This is a very large field, and there is way too much interesting detail to cover in one academic term;
• Primary emphasis on ecology, with diversions into anatomy, physiology, behavior, and communications at times;
• Strong emphasis on exposure to and practice of technical writing: WE CAN ALL USE THE PRACTICE!

Writing assignments
Research proposal:
• To be discussed in detail in this week’s lab sessions.
Critical reviews of published work:
• Two papers to be critically reviewed in writing, one that will be assigned, and one that you will select.
“Low stakes” writing:
• Four spontaneous assignments during lectures, always on a Friday. One paragraph minimum, one page maximum, full credit for honest effort to address the question posed.

Streamlining
Optimal shape for minimization of drag:
Length of body =3x to 7x maximum diameter(ideal is thought to be 4.5x)
