Not necessarily. Adaptations are changes in an animal's features or behaviour which enable it to live in a specific environment. Realistically, laying eggs is not an adaptation for a platypus, as it could just as easily bear live young in its chamber.
An example of an adaptation in a platypus is its feet - they are webbed for swimming but the webbing is retractable, exposing the sharp claws, with which it can dig its burrow.
Yes
A platypus reproduces by laying eggs. Like the echidna, it is a monotreme.
Yes. A monotreme is a mammal that reproduces by laying eggs. The two monotremes are the platypus and the echidna.
No, the only two egg-laying mammals are the echidna and platypus.
Yes. Like the platypus, the echidna is a monotreme, or egg-laying mammal. Monotremes are the only known mammals that reproduce by laying eggs.
Most mammals are not hatched from eggs. Only the monotremes, or egg-laying mammals, reproduce by external eggs. Monotremes include just the platypus, the long-beaked echidna and the short-beaked echidna.

The platypus is not a marsupial: it is a monotreme, which is an egg-laying mammal. Marsupials give birth to live young, and do not lay eggs. The other monotreme, or egg-laying mammal, is the echidna.
You're thinking of the platypus, which lays eggs and can eject venom. But the platypus isn't a marsupial. No marsupial lays eggs or is venomous. The platypus is part of a small group called the Monotremes.
A female platypus lays eggs which later hatch into young platypuses. The platypus is a monotreme, which is an egg-laying mammal, a characteristic shared only with the two species of echidna.
The Platypus (Ornithorhynchus anatinus) is an Australian mammal that lays eggs.
mammals Correction: There are two types of egg-laying mammals - the platypus and the echidna.
