Blue Whales Pirouette Before Engulfing Prey
by Tia Ghose
As if behemoth ballerinas, blue whales pirouette before lunging at their prey, a strategy that may help the giants ambush krill from below.
"This behavior probably improves the whales’ chances to engulf the most krill possible," said study co-author Ari Friedlaender, a marine biologist at Duke University.
The new findings, detailed today (Nov. 27) in the journal Biology Letters, may shed light on how the enigmatic creatures hunt and devour their shrimplike prey. Because krill cluster in massive swarms, “they’re perfect food for something like a baleen whale that wants to engulf a big amount of something at one time,” Friedlaender told LiveScience.
But while the marine mammals’ diet is well-known, how they find their prey remains a mystery…
