I think they're a little smarter than that, when they see a kayak they know there's bait nearby so down they go because kayak = bait

Another example
When you hoopnett the seals look for the glow stick and automatically dive right next to it because they know that glow stick = bait. One night I actually turned off all of my glow sticks and low and behold, the darn seal stayed away.
