Dann, that's a distinction I hadn't made: is there a definition for that
"pack"? I'd guess it to include the lions' pride.
"Even plants have their defenses. Some acacia trees produce toxins in their
leaves when damaged by a herbivore, then send chemical messages to all other
acacias down-wind, which will also begin producing toxins in anticipation.
Giraffes have learnt to feed on acacias in an up-wind direction, thus taking
their
victims by surprise..."
Interesting: plants with an active defense ("Once again, the giraffe has
outwitted its plant prey...")
