Another I need to know question from

[hippiepunk]

1. lays eggs

like the platypus

[Dookus]

2. Are you asking why

echidnas and platypi are considered mammals? It's because they are warm-blooded, fur-covered, and nurse their young.

[oneighty]

3. Slow down Dookus!

Birds are subclass of Mammals? Why? I ask. My ancient dictionary told me that. I am confused as I thought Mammals nursed their young by means of Mammary Glands. Birds do not do that.

[Dookus]

4. no no

I was asking what your exact question was, and I posited that you were talking about oviparous mammals.

Egg layers in general are NOT considered subclasses of mammals.

5. Curious

My 1930 dictionary says Oviparous are a subclass of Mammals.

[Dookus]

7. Can you please

ask the question again, and clearly? And can you post the exact definition you're reading in your dictionary?

11. monotremeata

the lowest sub-class of mammals, oviparous..

looks like I am misunderstanding. Excerpt from the dictionary; A single outlet for feces urinary and generative organs comprising only the ornithorhynchus and echidna.

Damn fine print. And I assumed they were including birds looks like?

180

[Dookus]

16. yes

I think you are misunderstanding. Oviparous is not a synonym for monotremeata, but a classification.

[oneighty]

18. Yes.

I see where I mis-lead myself.

Say oh wow! Chickens are Mammals? I never knew that!

So what are warm blooded chickens? Birds?

20. Thank you Dookus

6. Yes I was aware of the Platypus

[Squeegee]

10. Monotreme?

Monotremes are egg laying mammals. They are a subclass of "Mammal" just like marsupials and placental mammals.

[oneighty]

15. I am getting it straight now.

Thanks

21. Oviparous is an adjective meaning "egg-laying" --

Viviparous means live-bearing. Garter snakes are viviparous.

[oneighty]

22. Yes some snakes are

24. Welcome to DU Biology

I got myself into this dumb question because often when I am bored I read my dictionary. Reading my dictionary is fun! It is a Websters Encyclopedic Dictionary published in 1941. It has thousands of pages in very fine print concerning all sorts of interesting subjects.

I mis-read this subject (Birds a sub-class of mammals) and turned to the science forum (here)asked my question and had an answer within five minutes.

DU has it all!

Thanks for your response.
