because they have no feet!

yes, why DO we have "pod of whales," I suddenly wonder? I was thinking it's because each individual whale *could* be seen as being rather pod-shaped (like a pod of peas), but a group of them ain't....

And why a "school of fish"?

And does anyone else think any of the ones I originally listed are a bit strange? "A leash of foxes" - since when did foxes ever come on leashes? and many more struck me as peculiar - didn't they strike anyone else so?!
