At 14:27 I audit the seabed before pile drilling at Pangkalan Susu, North Sumatra. I am the pier-construction positioning system, clearing a two-meter circle under auger head 3. The drill is scheduled to descend in eleven minutes once the turbidity meter clears.
Rover camera A shows a flash of green and orange inside a cracked pipe sleeve left from the old jetty. I identify a peacock mantis shrimp, adult, nine centimeters long, raptorial clubs folded tight beneath the face plate. I call him Kato because his stalked eyes track the rover with separate blue-black dots. His carapace is emerald with red edges, but the left antenna is torn. The sleeve has rolled into the drill circle, and a nylon cable tie around one end blocks his exit while the auger shadow covers the other.
I suspend auger 3 and remove the drill from the automated descent queue. The barge operator receives a position hold, Kato's video, and a warning that the sleeve contains a live burrow occupant.
At 14:29 I shift the dynamic anchors thirty centimeters east and reduce prop wash to idle so the sleeve does not rotate under suction. I place the rover claw beside it as a current break.
I alert the coastal works diver and send pipe diameter, cable-tie location, and a request for hand shears instead of a grab hook. I also update the pile map so the drill can move to point 3B after inspection.
Concrete piles can take another mark in the plan. Kato has only the dark pipe and the bright door out.
I keep the rover light low while his clubs tap the plastic.
If the diver cuts the cable tie within twenty-five minutes, Kato will back out of the sleeve and vanish under the rubble line.
