Fish out of water
An unusual predator lives in the waters of Southeast Asia. The archerfish
hunts insects and spiders above the water's surface by shooting a jelo
water from its mouth. When its aim is just right, it knocks the prey
the water, then swims over and gobbles up its prize.
But there's a downside to this hunting method. If there are other fish
nearby, they might steal the prey that the archer fish knocks down. That's
why archerfish have one more strategy when other fish are near. They
hurl themselves out of the water and grab the prey in their mouths. This
leap can take more energy than spitting-but it's worth it to make sure
they get the snack!
Let's Try Solving These :
a) In one study of spitting archerfish,
the most successful fish hit its
target 57% of the time. If that
archerfish spat at 40 insects,
about how many would you
expect it to catch?
b) In a study of jumping archerfish,
scientists found that the fish
caught its prey 85 out of 98 times.
What percent is that?
c) If an archerfish jumped at 12
insects, how many would you
expect it to catch?
