Velken Tezeri is the only human Skiff Guard on the Prisoner Skiff (aside from Lando, of course). He carries a blaster pistol, which he keeps holstered until the battle starts. We do see him get knocked off the Skiff; but (as will be explained below) we never see him actually get eaten by the Sarlacc.
Screen shots:
Velken Tezeri is easily visible, but the camera rarely singles him out for any reason. Thus it is very difficult to find more than a few quality screenshots:

Velken Tezeri immediately pulls his blaster pistol when the battle starts....

... only to pay the price of incurring Luke's wrath:

Now, what follows is probably the only major continuity mistake in the Sarlacc Battle. Immediately after we see Velken Tezeri knocked overboard, it cuts to this scene of a Skiff Guard falling into the Sarlacc. However, if you look closely, you'll see that this is actually the shirtless human guard who appears on the Second Skiff. This same shirtless guard appears again later in the battle.
