Some species of fish are being caught, or havested, and consumed so quickly that their numbers are dwindling. Many are endangered and even face extinction due to overharvesting. Some are listed as endangered species, while others aren't recognized on any official list.

When buying fish, avoid species you know are at risk. Sometimes fish have different names depending on where you are or from whom you are buying. Use this activity to explore examples of threatened species—being able to identify a fish by the way it looks can help you decipher what species you are actually buying, and which fish to avoid!
