Teenage hormones rage
Sex class for understanding
No babies too soon!
Photosynthesis
Basic plant process for life
Still not understood.
Now Zoology
The study of backbone ones
We are amongst them.
Embryology
Ernst Haeckel outlined so much
Showed phylogeny.
One's ontogeny
Outlined the other life forms
Gills to a real tail.
Gill slits of a shark
Webbed digits--both hands and feet
We came through the past.
Invertebrates, though
Do not have proper backbones--
Exoskeletons!
Armadillo--shelled
Eats insects plus lots of stuff
Digs many burrows.
Anteaters with scales
A kin to armadillos
Scaled, but not a shell.
Both have sticky tongues
Forty thousand ants per meal
Much formic acid.
Ornithology
Dinosaurs gave rise to birds
Oh, if I could fly.
Pre co ci ous ones
Leave the nest in quickest time
Others sit ten days.
Mother duck must groom
Ducklings have no py gial gland
Oil for buoyancy.
Learn to swim so soon
Natural with web bed feet
Move fast all around.
Some ducks dive, some don't
Those others are called dabblers
They eat from the top.
Male Mallards--green heads
Females' brown to camouflage.
Hiding on their eggs.
Molting part of life
New feathers come to replace--
Worn out, Flight now ceased.
Ratites are flightless
Having large legs--useless wings
Careful of those legs!
Ratites grazed with cows
Very good polyculture
Such modern farming!
Ostrich eggs so large
Lone egg, largest single cell
Giraff's neck cell close.
