It's holding up 3300 pounds. Pounds is a unit of weight.

> Even so, spaghetti strand is not known for strength or tension resistance even when considering the weight/size/volume.

That's...kinda the point? We have something we don't give two thoughts about (slug tooth) comparable in scale to something not known for strength or tension resistance (spaghetti) holding up to something ginormous as if it's magic. Clearly, we should study slug teeth more!

Imagine if a strand of spaghetti can hold 3300 pounds. It's not possible with spaghetti but with slug teeth, it is! Now imagine the possibilities!
