do rats have bones

[zgma]

Yes they do, as they are vertebrates.

[football]

Rats do have bones because they are mammals.

Football - having bones is not the definition of a mammal - they are defined by giving birth to live young which they suckle, apart from the duck-billed platypus which lays eggs, but suckles its young - there's always one exception to the rule.

[Phantaxus]

I think i am in correct in saying that the DBP is the only poisonous mammal. (at least until corrected by a fellow ABer)

[New Forester]

Phantaxus - You weren't quite right, I'm afraid... Many shrews have a poisonous bite. Also, one of those odd little primates (I think the slow loris) is poisonous to eat, or to touch, or both. Doesn't it have poisonous saliva with which it coats its fur? Andy - I read football's logic to say: they are mammals, mammals have bones, therefore rats do have bones. Zgma - Not quite all vertebrates have bones. Sharks & rays (Elasmobranchs) have a skeleton, but it is made of cartilage (gristle) not bone. Though I suppose you do have to call the various bits of the skeleton "bones-made-of-cartilage" or something. I think some amphibian "bones" may not be bone either.
