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.
Quite often we will observe one humpback whale following the shoreline with the intense purpose of feeding. Every 200 to 300 meters the whale will take a few shallow breaths, then arch its back to prepare for a deep dive. Our last sight is that of the tail fluke.
