Platypus
A mammal that lays eggs and finds prey using electrical signals. Read how its unusual features work together in a life spent between water and land.
Look closer at the bill: how can an animal sense prey with its eyes closed?
An egg-laying mammal. A giraffe’s unexpected relative. A tiny animal built for extremes. Start with a surprise, then follow the science.

Striped legs suggest a zebra; the family tree points to a giraffe. The okapi is a reminder that the most obvious resemblance is not always the closest relationship.

Those overlapping scales belong to a mammal. Start with their keratin armor, then follow the story into an animal shaped around finding ants and termites.
Compare form and food: what do scales and a long tongue each make possible?
Small enough to miss, interesting enough to spend an afternoon on. Some tardigrades can enter a low-activity state that helps these microscopic animals survive extreme conditions.
Read the limits too: survival in a dormant state is different from thriving.
Not quite a fish, and not just a pair of tentacles. This cephalopod can change its appearance, making camouflage a much more active process than simply having the right color.

Compare a platypus’s sensory system with an axolotl’s life in water. Follow a pangolin from its scales to its diet. These reading connections are a starting point, not a checklist you need to finish.
