Why do platypus not have stomachs?
The pufferfish was the sole exception—like the platypus, it has kept a single pepsinogen gene, which it uses for non-digestive purposes. “It’s a clear-cut pattern of gene loss and stomach loss across all of these species,” says Wilson. A family tree of vertebrates, showing those that do and don’t have stomachs.
Are platypus eggs edible?
Exclusive to Australia, New Guinea, and Tasmania, the platypus and the echidna are the only two mammals known to lay eggs! These are two types of eggs which are definitely not suitable for eating. A platypus egg is pretty small. At not even a ½ inch in diameter, you’d need a whole bunch!

Why doesn’t a platypus produce yolk proteins?
The platypus isn’t as dependent on creating yolk proteins as birds and reptiles, since it produces milk for its young. In all other mammals, casein genes have replaced vitellogenin genes.
