Watch & Question: Creek

During the flood disaster, the seawater flowed in and out of the polders, eroding deep gullies. The dikes have now been closed, but the water in the gullies has remained. That is why beautiful creeks have now formed here, where you can find birds and other animals. You might even see a lizard dart away. In the water, you can also find fish such as the eel, the flounder, and the rainbow trout. This fish can be recognized by its black spots. But there is one place on its body where there are no spots. Follow the route and look around carefully, and you will learn more about the rainbow trout.

Question 4: Where on its body does it have no spots? Take the 2nd and 3rd letter of the answer.
