Just imagine: one fine day, a fish revealed to you …
With proto-limbs, a monstrous face, all tinged with silver-blue!
Huge and strange and other-worldly, long thought to be lost,
In the flesh (starting to smell!) so many epochs crossed.
The coelacanth! Good Old Four Legs, to some, the “Living Fossil,”
The animal itself is big, its history colossal!
Ms. Latimer, she recognized its weirdness and allure;
Decades later, of its story some things were not sure.
But now we have its genome clear and plain for all to see,
Shedding light on autopods, immune systems, and pee!
More closely tied to humans than to tuna or to trout,
Holding secrets of the beasts who from the sea, climbed out.
