I had to look up burgeon in the dictionary today. The first word that came to mind was sturgeon. Yes, my mind is a twisty biscuit. Sturgeons are, or should be, an endangered species, but for some reason they can still be fished, in limited places for limited times. I would encourage you to click on the image links if you are interested in learning more about these prehistoric critters.
When populations of snails do burgeon,
Then it’s feeding time for sturgeon
When populations of clams do grow
Then it’s time for the sturgeons to mow
When larvae swarm the lake’s floor
Sturgeons munch them and ask for more
When the fish eggs, roe, do come
The sturgeons dine and say num num num!
