A lot of people enjoy eating clams in the daily life, but few have notice how they would interact with environment surrounding them. By the means of siphoning water and then filtering it for plankton, clams get the necessary food. However, a recent video should be surprising to you, because it presents the vivid description of how a clam could lick salt from a table via its ‘tongue.’

In fact, its ‘tongue’ is the foot of the clam, by which the clam would be able dig and anchor to its surroundings, therefore it is not really about eating anything at all.

As Miriam Goldstein, the biologist from Scripps Institution of Oceanography said, possibly the clam was making efforts to find out a place to dig, so he was doubted that the salt should have relationship with it.

When giving some explanations for such behavior, Goldstein added that there was the possibility demonstrating the salt on the table hurt the clam, so it had to withdraw its foot after touching it. Another possible reason why it did this should be attributed to the fact that the clam did not show little interest in the salt at all.
