Notonectidae (Achievement #70 = 5 points)

The Backswimmer swims upside down,

in the pond it spends its days

chasing lunch and dinner round and round,

No breaststroke for this insect,

breaststroke, crawl, and butterfly,

all of them it does reject.

Upside down under the water

is where you'll find the Backswimmer,

a bug that won't swim like it oughter.
