🦆 The Platypus Has No Stomach & Breaks Science

The platypus feels like evolution hit randomize.

Eggs, venom, glowing fur, and no true stomach.

Platypuses are mammals, but they lay eggs instead of giving live birth.
Males have venomous ankle spurs.
They also lost the genes needed for a highly acidic stomach, so their food moves from esophagus to intestine with no true stomach chamber.

🦆 Monotreme → An egg-laying mammal
🧪 No stomach → Lost key acid-digesting stomach genes over evolution
✨ Biofluorescence → Platypus fur can glow blue-green under UV light

Reality check: Scientists do understand a lot about platypuses. They are not “broken,” they are in fact a rare surviving branch of mammal evolution.
