What makes us mammals?
- Precise tooth occlusions, and molars that fit together perfectly.
- three middle ear bones
- 2 sets of teeth
- hair
- mammals produce milk (i believe even egg layers do)
- body heat

Samba - there are 3 mammals that lay eggs that I know of, the Platypus and two species of echidna

dont know about two species of Spiny Anteater, but the spiny and the Platy both lay eggs.

For bonus points, how many venomous mammals are there?

Well, that depends on your definition of venomous. Venomous and Poisonous are not the same thing.
Poison: A substance that causes injury, illness, or death, especially by chemical means. (includes venom)
Venom : A poisonous secretion of an animal, such as a snake, spider, or scorpion, usually transmitted by a bite or sting.

Now, presuming you are refering to poison and not venom, i'm not sure of the exact number but the duckbilled platypus (males only), several species of shrews (short-tailed shrews namely, are neurotoxic. also the European water shrew), and the Solenodon (a small insectivore) are poisonous.

So that's about 4? Whats the exact number?

Yep, but some of these mammals are not considered venomous, but poisonous.

I really dont think theres to much debate out there on the comparison of the two words...... If there is, what yahoo search did you do to find it?

actually, on my search for different poisonous mammals I encoured many occurences of "venomous and poisonous are not the same thing". Following this, I used a couple dictionaries (online and book) to find the definitions of each word which were clearly different.

The debate is not important when dealing with spiders and snakes (they are both poisonous and venomous) but they are when dealing with animals that, say, excrete a toxin from their skin or claws, such as platypus, poison arrow frogs, and 2 species of birds.

Actuyally, the platy is venomous, not poisonous. The main difference is that the poison has to be injected into the blood stream or lymph system.

But yes, Platys and shrews are venomous.

heh you sure BW? Everything I read said the opposite. I doubt this'll be resolved unless either of us become micro biologists, but anyway :P

I know venom is a poison, but I thought the main difference was that venomous requires a delivery system like fangs or other specialized organs, which the plattypus posseses, but also is used for predation, which the plattypus doesn't so simply by default the plattypus is termed poisonous while still not fulfilling the requirements of either, while poisonous is a toxin that is in part or all of the body and usually requires attempted ingestion? Anyway I hadn't seen the solenodons mentioned which should complete the list platties, some shrews, and the solenodons.

None of the above apply to Dolphins, but they are mammals....

Dolphons I believe have all of the above, I know they nurse their young with milk and I beleive that whales and dolphins have tiny hairs all over their bodies. Dolphins are also warm blooded which means body heat. I'm not sure about the teeth either but I think they also have aligning teeth. But I know they have at least one of those. They also breath oxygen from the air like us not filtered from water like fish[blowholes].
