Animal Kingdom

If an animal gives milk
Like a cow or a camel
It's a mammal

All the worms in the Earth
And all of their kids
Are annelids

Creatures with external skeletons
And segmented bods
Are arthropods (like a crab or an insect)

Single-celled, microscopic
Creatures, you ought to know-a
Are protozoa (like amoebas and flagellates)

Mammals that live in the water
Needn't fear dehydration
They're cetaceans (like a whale or a dolphin)

They're all part of the animal kingdom
