Whale Shark: Identity crisis?

First of all, I am blown away by the detail put into the underwater zones, but I got a chuckle out of the new Whale Shark mobs swimming around. I love the way they look, but they have one major flaw.

Someone must have goofed and started with a "whale" skeleton instead of a "shark" one and used the whale animations, because they swim with the up-and-down motion of the in game whales. Not the (correct) side-to-side motion of a shark.

Anyone else sit there gawking at them and wondering how in the world that got by the QC department? I laughed.
