       | chickens, or eat them with rice'

       | One of my early childhood memories was crayfishing. You can
       | pretty much put anything on a string and these things will bite
       | onto it. They are not picky. It's not even really fishing, it's
       | almost as easy as just grabbing them from the water. It's a fun
       | activity for kids because it doesn't require any skill to get
       | good at.

       | They are an indicator species. They are not known for tolerating
       | polluted bodies of water and quickly die if the water becomes
       | toxic.
