Hello there!

Yesterday, we went to the mall to buy groceries. We typically buy in the mall instead in public market because it is more convenient for us. So, yeah. And when we were in the fish section, while choosing what fish to buy, I found this fish with a smaller fish still stuck in its mouth. What could have happened?

I tried to pull out the smaller fish out from the mouth of the bigger fish, but then did not continue to do so. 

What could have happened?
