Isn, a Migratory Fish?

This is a, i'm really getting a sense that this animal isn't just a bit of a wandering hippy that just goes where he wants and does what she os a preditor. This is an active predator that's using vision to to hunt ina range of different environments. I think what's been really clear for me so far is there's lots we don't know. Such an iconic, big, globly migratory fish is is. But we've not quite finished yet, are we?
