FAQ
Frequently Asked Questions
'Platypus' is sufficient for most contexts. 'Duck-billed platypus' is the full, formal name and is often used in writing or for emphasis.
Yes, it is a mammal, specifically a monotreme, which means it is a primitive, egg-laying mammal.
No, 'platypi' is a common error based on a false Latin analogy. The correct plurals are 'platypuses' or simply 'platypus' (used for both singular and plural in scientific contexts).
They are not aggressive, but male platypuses have venomous spurs on their hind legs, which can deliver a painful sting to humans.
