Spider "Resurrections" Take Scientists by Surprise

Charles Q. Choi's article "Spider 'Resurrections' Take Scientists by Surprise" provides information on the new discovery made by scientist. Scientists have recently observed that "spiders in a lab twitched back to life hours after 'drowning.'" Choi supports his claim that spiders can come back to live after drowning by providing the results of an experiment done in France with the unexpected results. The experiment was done to see how long it takes certain spiders to drown. After the spiders drowned the researchers let the spiders dry so they can weigh them and that is when they saw the spiders twitching and soon they were back on there eight legs. The researchers say that spiders have learned to switch to metabolic processes so they can survive without breathing for a certain amount of time. Choi claims that this discovery can lead to find out what other animals have the ability to do this trick that the spiders did.
Discussion Questions:
Clarification: Do all spiders know how to switch metabolic processes or are there only certain types that have this ability?
Application: How can researchers find out if other animals have this same abilities as the spiders?
