Interactive 3DCompare body plans across seven animal groups — from sponges to mammals.
Controls
Drag the sliders or type a value — the simulation updates live.
Study notes
Seven body plans, one slider: a sponge (no true tissues), a jellyfish (radial symmetry), an insect (exoskeleton, 6 legs), a fish (gills, fins), a frog (dual life), a bird (feathers, beak), a mammal (hair, mammary glands). Each step up adds a key innovation in animal evolution.
