The escaping spiders clocked some impressive statistics: their average peak speed was 65 centimeters per second, with an acceleration of 200 meters per second squared. That’s equivalent to 20 Gs, or 20 times the acceleration felt during freefall.
Zhang said he believes the females were judging males’ sexual suitability by their ability to escape.
“Through the catapulting, a male can escape female sexual cannibalism, and a female can choose males with high quality, because the kinetic performance may directly correlate with male’s physical condition,” he said.
Even though they have already mated, females may go on to only accept the sperm of males that passed the test, explained Zhang.
And guys think we have it rough asking a girl to dance.
So much for the definition of a Canadian as someone who knows how to make love in a canoe:
From accidental tent burning with hot lanterns to flood-related issues due to rain-filled tents, the majority of respondents, 39 per cent, who were asked to rate their own level of camping competence confessed that their skills are poor at best, if not outright dangerous. Only 36.3 per cent of Canadians rated themselves as ‘ok’.
Naw, I think Canadians are invested in this image of themselves as rugged outdoors people, when actually most people these days are pampered city-dwellers- not that there’s any thing wrong with that.
