# A Not-So-Friendly Frog

April 14, 2018

If you want to have a pet frog, don’t get a really colorful one. That bright, tropical-looking frog might be a poisonous dart frog. Dart frogs come from Central and South America, and you can spot them from their bright greens, pinks and yellows. They’re also called poison arrow frogs, because long-ago people took the poison from the frogs’ skin and smeared it on the tips of their arrows. Even crazier, some scientists think the frogs stay poisonous by eating special insects, who turn poisonous by eating special plants! The most poisonous dart frog has enough poison in it to kill 10,000 mice…yikes. Those bright colors warn other animals like mice not to snack on them. So if you already have other pets, this might not be the best buddy for them.

Wee ones: Dart frogs come in bright shades of red, orange, yellow, green, and blue. How many frog colors is that?

Little kids: If you get 2 frogs of each of the 5 colors, how many poisonous pets do you have?  Bonus: If you buy 2 frogs, twice as many poison beetles to help them out, and 5 poison plants for the beetles, how many poisonous things do you have?

Big kids: These frogs are only about 2 1/2 inches long. If you can fit 2 of them end to end on your hand, how long is your hand?  Bonus: Some frogs jump 50 times their body length! If a 2 1/2-inch dart frog could do that, how far could it jump?
