From a reader:

Hey Jonah,
You said they could not be found. But I say, behold! The snail darter honored in verse!
I think and I think, but it couldn’t be harder,
To say something noble about the snail darter.
It’s small, it’s wriggly, and despite how you wish,
In the end and beginning, it is just a fish.
Teams called “Snail Darters” are absent in sports,
And few lawyers are dubbed “the snail darter of torts.”
Now, tigers are big and stealthy and swift,
Making small fish fans regrettably miffed.
But the wee snail darter has one claim to fame,
A great feat a tiger can never proclaim;
Yes, tigers all over will have to be slammed,
A tiger has never, ever knocked down a dam.
