Weird parasite

[Peter B]

I got a sand sifting sea star today, and right when I plopped it in, this weird little bug swims across the bottom of the tank about an inch above the sand. Luckily(?) My chalk bass ate it within about 2 seconds of my seeing it. Anyone know what this is? Unfortunately I couldn't even focus on it before it was consumed. Should I be concerned (whether there is more, and/or if the chalk bass will be okay)?

I thought about that but it was pretty big-- probably about .75 cm long and 5-6 mm wide
