# Return of the Super-Sized Stingray

April 16, 2019

Life as a fish can’t be very exciting, except when some other animal tries to catch you. Well, this stingray has been caught twice by fishermen, and broke a world record both times! Stingrays are very flat, wavy fish with a spike in the back to scare off attackers. Fishermen in Thailand caught a huge stingray that was 8 feet wide — on its side it would stretch from your bedroom floor to the ceiling! It was 14 feet long and weighed between 700 and 800 pounds, making it the world’s biggest stingray. The crazy part is that this same stingray was also caught in 2009, when it was just 6 ½ feet across but 15 feet long (its stinger had broken since). Clearly this fish just likes to show off for us.

Wee ones: A stingray is almost shaped like a circle. Find 4 circle-shaped things in your room.

Little kids: If the stingray was 6 feet long last time and 8 feet long this time, what counting number did we miss in between? Bonus: If you lay facing forward on that 14-foot stingray to ride it, how much longer than you would it be? (You can round your height to the nearest foot.)

Big kids: If the stingray grew from 6 1/2 feet wide to 8 feet wide, how many feet did it grow? Bonus: If you line up a bunch of 14-foot-long stingrays end to end, how few 6-foot-tall people can line up end to end to match exactly a whole number of stingrays? What’s the smallest number that works?
