WildLens

Every living thing has a place in the web of life — and clues that give it away. Read an animal's field marks to name it like a naturalist, build each habitat's food web and follow the energy from the sun to the top, and learn how living things fit together. No camera and no photos needed — you identify by the clues.

Level 1

Species Detective

Identify wildlife the way a field naturalist does — by its clues, on any device, no camera.

🔍 Open Species Detective Read the field marks — group, habitat, diet, when it's active, size — and narrow to the one species. 50 real North American species.

Food-Web Builder

Put a habitat in energy-flow order and see why food chains stay short.

🕸️ Build a Food Web Start with the producer, follow the energy up through the consumers, finish with the decomposer — across six real habitats.

Ecosystem Cascade

Remove one species and predict what happens to the rest — the ripple through a food web.

🌊 Predict a Cascade Take a species out of a habitat and work out whether a connected animal's numbers go up (a hunter is gone) or down (a food source is gone).
