Trapped underwater, a female salt marsh-dwelling wolf spider
(seen in an undated photo)--one of 120 in a recent experiment (full story
)--is on the verge of drowning, and "resurrection."
Salt marsh wolf spiders enter comas to survive for up to 24 hours underwater, but after that they finally die. Or so scientists thought.
After up to 40 hours underwater, the researchers, in hopes of weighing the motionless spiders later, laid them out to dry. Hours later, they twitched back to life, surprising the scientists.
"This is the first time we know of arthropods returning to life from comas after submersion," lead researcher Julien Petillon said in April 2009.
