BODY PLAN 6 PHYLA 3

(Verse 1) In the vast expanse of life's display, Where creatures thrive in their own way, Six phyla stand, distinct and grand, Each with a form, a story planned. (Chorus) Porifera, the simplest of all, With pores that filter, big and small, Asymmetrical, no head to find, Diploblastic, a simple design. Cnidaria, with stinging cells, Radially symmetrical, their beauty compels, Diploblastic, with tentacles that sway, A gastrovascular cavity, their food highway. (Verse 2) Platyhelminthes, flat and thin, Bilateral symmetry, a new skin, Triploblastic, with organs galore, Acoelomate, no body cavity to explore. Annelida, segmented and long, With a coelom, their bodies strong, Closed circulatory system, blood flows free, Complete digestive tract, for you and me. (Chorus) Arthropoda, with jointed limbs, Exoskeletons, their armor glints, Bilateral symmetry, a complex plan, Triploblastic, with organs in hand. Chordata, with a dorsal nerve cord, Notochord, a support to afford, Bilateral symmetry, a head to lead, Triploblastic, with organs indeed. (Bridge) From simple sponges to complex forms, Evolution's tale, a story warms, Mode of life and body plan, A symphony of nature's grand plan. (Verse 3) Porifera, filter feeders, they, Cnidaria, stinging prey, their way, Platyhelminthes, parasites or free, Annelida, burrowers, in earth or sea. Arthropoda, with diverse array, Insects, spiders, crabs at play, Chordata, vertebrates we know, Fish, amphibians, reptiles, birds, mammals in a row. (Chorus) Symmetry and cephalization, Tissue layers, a stratification, Coelom and blood, a complex design, Gut and digestive, a vital line. (Outro) Six phyla, a wondrous sight, Each with a form, a unique might, Mode of life and body plan, A testament to nature's grand plan.
