Invasion of the Lionfish

Invasion of the Lionfish

November 18, 2020

Lionfish are — you guessed it — fish that kind of look like lions. These spiky, stripy sea creatures are beautiful, but they’re poisonous. Worse yet, they’re taking over the Atlantic Ocean. They don’t normally live in the Atlantic, so they have no “predators,” or animals that like to eat them (this is where being poisonous comes in handy). They just keep having new baby lionfish, who have more baby lionfish. One lionfish can lay 30,000 eggs at a time! So they’re eating up 90% of the fish that live in Bermuda’s coral reef. 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: How many white-tipped spiky fins does this fish have along the top? Count them up!

Little kids: If every other fish you catch is a lionfish, starting with the 2nd fish, is your 9th fish a lionfish?  Bonus: How many lionfish have you caught by then?

Big kids: 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?  Bonus: If 25 restaurants in Florida each serve 2 lionfish each night, how many fish can they all serve in a week?

 

 

 

 

 

 

 

 

 

 

 

Answers:
Wee ones: 11 fins.

Little kids: No, it’s some other kind of fish.  Bonus: 4 lionfish (the 2nd, 4th, 6th and 8th).

Big kids: 180,000 fish.  Bonus: 350, since together they serve 50 per night.
