I interviewed at Bi-Mart (Madras, OR) in September 2016. The interview lasted about 25 min and was extremely laid back. He spent more time talking about Bi-marts operations and friendly, for the employee, work place then anything else.
Confidence votes 13. Whales, like otters, porpoises, and all other swimming mammals, undulate their spines rhythmically, waving their tails and flipping the flukes at the end, propelling them forward.
Moreover, whales (and dolphins) have some control over their penises: they can move it and - to a certain degree - bend its tip to facilitate mating! In a way, we were expecting this result, but this is like a human having a 10 cm penis, because the blue whale can reach 33 m (100 feet) body length.
