Lionfish look cool with their stripes and spikes, but they’re poisonous and taking over the Atlantic Ocean. They have no “predators,” or animals that like to eat them, and one lionfish can lay 30,000 eggs at a time! Luckily, lionfish are very tasty to us people, and we can eat them without being poisoned. The question is, can we eat up all these fish before they eat everyone else?
Wee ones: What shapes are on top of the fish’s glittery gold crown?
Little kids: If every other fish you catch is a lionfish, starting with the 2nd fish, is your 9th fish a lionfish? Bonus: If you catch 2 dozen lionfish, ow many lionfish have you caught? (Reminder: 1 dozen = 12.)
Big kids: If 25 restaurants each serve 2 lionfish each night, how many fish can they all serve in a week? Bonus: All lionfish appear to be the great-great-great…grandchildren of just 1 of a set of 6 fish. If those 6 fish each laid 30,000 eggs, how many new baby fish did they have in total?
Answers:
Wee ones: Circles, or “spheres” in 3D.
Little kids: No, it’s some other kind of fish. Bonus: 24 lionfish: 12 + 12.
Big kids: 350, since together they serve 50 per night. Bonus: 180,000 fish.
