I have witnessed large schools of adult size bass working together to heard prey on several occasions that resulted in phenomenal catches. I wouldn't limit wolf packs to juvenile bass.
Also watched large schools of bass traveling across wide deep expanses of water,both largemouth and Smallmouth.
Standing on a high bluff above the water at lake Havasu a massive school of largemouth bass, several hundred, swam across the lake from the opposite shoe to where I was standing, it look like a cloud shadow.
When the giant school of bass neared the shore they split up, some swimming up the lake, some down the lake and into coves. Mass migration?
Lake trout fishing on lCrow lake in Ontario Canada, we were jigging for lakers about 5 miles off shore when a big school of Smallmouths passed under our boat swimming toward the opposite shore, another mass migration?
Spend enough time on the water and you will discover bass behavior isn't always predicable.
I watched a strange behavior at Little lake near Fossil Falls north of Mojave.little lake is about 1 mile long maybe 1/8 mile wide water filled volcanic fissure that is over 1,500 feet deep in the fisher crack that runs about 1/4 mile long in the center of this lake, the rest is shallow about 3' to 10'. The largemouth bass in Little spend most of their time in the deep fissure along the walls, then move out toward the shore to herd baitfish back into pockets along the shore, feed and return to the deep fissure crack that supplies the lakes spring water. Adaptive behavior that suits the ecosystem.
Schools of big bass feeding on planted rainbow trout is another example of adaptive behavior.
