Schreckstoff
Schreckstoff is a German word that translates to "fright substance". It's a chemical compound that some fish produce when they are scared or injured. When other fish detect the schreckstoff in the water, they become afraid too and try to swim away to avoid danger.
Think of it like when you see a bee sting someone and they scream. You become afraid of the bee because you don't want to get stung too. The same thing happens with fish and schreckstoff.
Scientists have found that some fish, like minnows, can produce schreckstoff in response to other fish's distress signals. This helps them to avoid becoming prey and stay safe in their environment.
Overall, schreckstoff is an important way that fish communicate and protect themselves from danger.
