Squid can hear! And why it may matter…

Science, Seismic Surveys, Shipping Add comments

A month or so ago, new research by Aran Moody at Woods Hole was published and garnered a bit of press attention — perhaps largely because it involved squid, whose public fan base rivals that of their more “charismatic” brethren, the whales and dolphins.  I’ve been meaning to post about it, but didn’t get to it.

Just as well, because today, Canada’s MacLean’s magazine blogs the story just right, offering the best mix of science and why it matters that I’ve seen.  The key points are that squid appear more sensitive to low-frequency sounds or pressure waves (such as that perhaps preceding the approach of a whale, rather than the echolocation clicks of dolphins), and this could mean that shipping or seismic surveys may displace squid.  There’s also a chance that invasive squid species, such as the Humboldt squid decimating fisheries along the northeast Pacific coast, could be chased away with noise (oh, joy!).  Check out the full post at MacLeans here.
