Do penguins have a way to test the ice that they stand on to ensure that the ice will not break? In other words, do penguins make sure that they will not fall into the ice before stepping onto it?

I have conducted research but have come up short, which made me assume that penguins don't test the ice. However, I wanted to make sure before I just made an assumption.

  • $\begingroup$ @BryanKrause They would fall into the water; they would be startled, but if the conditions are right, then they will be able to swim under the water, correct? $\endgroup$ Mar 17 at 16:44
  • $\begingroup$ I could also envision a scenario that the ice reseals, thus trapping them under the ice -- perhaps a great distance from the next breathing hole. Seems like an interesting question to me. Please edit your post to explicitly indicate what type of research you've already done. (You say you've "come up short", but where did you specifically look and what have you learned along the way?) $\endgroup$ Mar 20 at 1:49
