Friday Squid Blogging: Best Squid-Related Headline

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/07/friday-squid-blogging-best-squid-related-headline.html

From the New York Times: “When an Eel Climbs a Ramp to Eat Squid From a Clamp, That’s a Moray.” The article is about the eel; the squid is just eel food. But still….

Friday Squid Blogging: Live Giant Squid Found in Japan

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/02/friday-squid-blogging-live-giant-squid-found-in-japan.html

A giant squid was found alive in the port of Izumo, Japan. Not a lot of news, just this Twitter thread (with a couple of videos).

If confirmed, I believe this will be the THIRD time EVER a giant squid was filmed alive!

Friday Squid Blogging: Squids Don’t Like Pile-Driving Noises

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/01/friday-squid-blogging-squids-dont-like-pile-driving-noises.html

New research:

Pile driving occurs during construction of marine platforms, including offshore windfarms, producing intense sounds that can adversely affect marine animals. We quantified how a commercially and economically important squid (Doryteuthis pealeii: Lesueur 1821) responded to pile driving sounds recorded from a windfarm installation within this species’ habitat. Fifteen-minute portions of these sounds were played to 16 individual squid. A subset of animals (n = 11) received a second exposure after a 24-h rest period. Body pattern changes, inking, jetting, and startle responses were observed and nearly all squid exhibited at least one response. These responses occurred primarily during the first 8 impulses and diminished quickly, indicating potential rapid, short-term habituation. Similar response rates were seen 24-h later, suggesting squid re-sensitized to the noise. Increased tolerance of anti-predatory alarm responses may alter squids’ ability to deter and evade predators. Noise exposure may also disrupt normal intraspecific communication and ecologically relevant responses to sound.

Press release.
