Blue Whales, Unused To Dodging, at Risk From Ships: Stanford Biologist

"Blue whales are vulnerable to cargo ship strikes because they are so used to being the largest animal in the ocean that they often fail to avoid the vessels, a Stanford University biologist has found.

The study published in the latest edition of the journal Endangered Species Research is based on direct observation in the waters off Southern California, where a team used GPS technology and suction cups to track how the giant mammals respond when a vessel is barreling toward them.

Researchers found that blue whales, instead of diving sharply, responded to approaching ships by descending gradually at a rate of just over a foot and a half (0.5 meter) per second, and did not try swimming to one side, according to Stanford University."
