Certainly a rat isn't so tough, but what are its other stats like? Does it low low HT?
As of 3E, a rat has ST 1, 2 Hit Points, and HT 17.

There are lots of large but fragile animals in existence, which is why I don't see a connection.
If they are fragile, are they still physically strong?

Sure, but it takes a bigger exposure to pathogens or poisons to debilitate the T-Rex.
Well, I've checked now, and they still have a HT of 15. That's pretty tough. Still, HT is normally something you roll against, and thus you will hardly ever see a creature with more than a HT of 17 (like with rats) - but there are plenty of creatures with dozens of hit points (50-75 in the case of the T-Rex). And these tend to be big and strong.

Personally I think they should split HT into stamina and durability (or something that sounds more scientific than durability).
Stamina = fatigue pool. Durability = hit points. It fits.

A rat would resist poisons and disease better than a human would, but then again a stomp is still a stomp to a rat.
Remember, any creature is dead when it reaches -5xhit points, or -10 in the case of the rat (-5 if they adjust hit points to the ST 1 of the rat in 4E). Sure, it will probably make its HT rolls until then, but enough damage does kill it pretty easily.
Remember, "surviving damage" is only represented by hit points in d20 - but by hit points
and HT in GURPS. It was just that the former was based on the latter in 3E, which lead to some pretty weird results in the case of especially large or small creatures.

I haven't seen evidence that a person who can run for long periods of time is more resistant to pain or death than other people.
Well, if someone suffers massive trauma, I do think it helps if his internal organs function at peak efficiency...
