Clams
siphon water and filter it for plankton,
this is how they eat. What appears to be a 'tongue' is actually the clam's
foot. It is used to anchor itself in
the bay and ocean's floor.
"It's probably trying to find a place to dig. I doubt the salt has anything to do with it," said Scripps Institution of Oceanography biologist Miriam Goldstein to io9.
"It is possible that the salt on the table is hurting the clam, which is why it withdraws its foot after touching it," the biologist told the Daily Mail.
"It is also possible that the clam does not care about the salt at all."
