Choose a published field note, then use the same repeatable lesson structure. No student accounts, names or scores are collected.
Male sarcastic fringeheads settle disputes over shelters not by biting but by pressing their wide-open mouths together in a shoving match, a contest where mouth size, not body size, often decides who retreats.
The kagu, a ground-dwelling New Caledonian bird, has fleshy movable flaps called nasal corns covering each nostril, a structure not documented in any other living bird species and linked to its habit of probing leaf litter.
Loggerhead shrikes spear insects, lizards and mice on thorns or barbed wire, using the spike as a substitute for the strong grasping talons they never evolved.
The sea angel Clione limacina hunts almost nothing but shelled pteropods called sea butterflies, extracting them from their shells with a retractable set of hooked buccal cones rather than a radula alone.
Anglers often treat them as separate fish, but steelhead and rainbow trout share identical DNA. The only difference is a lifestyle choice: whether a young fish swims to the ocean or stays in its home river.
The ground pangolin's tongue does not attach at the throat like most mammals. Instead it runs back to the pelvis, letting the animal unfurl a probe longer than its own body deep into insect nests.
Atlantic mudskippers spend most of their active hours out of water, absorbing oxygen through their skin and mouth lining rather than relying only on gills, a trait called cutaneous respiration.
Before reaching sexual maturity, female fossas grow an enlarged, spine-covered pseudo-penis and rust-orange fur matching adult males, a disguise thought to reduce harassment, then lose both traits within a couple of years.
