Parade of Extant Chordates

[Grace]

Yeah, this definitely isn't a good poem. Just my hand at writing doggerel (but, you know, scientific doggerel.
But aww, I was hoping the whole fact that I wrote about such an obtuse subject would be funny enough. Perhaps I should tighten it?

Well, I did find it funny. Maybe it's just me, but 3 stanzas down, it started to sound like Monty Python. It's informative, with hilarity thrown in.
