the arms and legs. Waggled the head. Blew some air -- air! lungs! wet squishy things down there in the chest cavity -- out between the lips.
"All OK?" the rowboat-him asked the meat-him.
"I'm in," he replied. He looked at the air-gauge on his BCD. 700 millibars -- less than half a tank of nitrox. He spat in his mask and rubbed it in, then rinsed it over the side, slipped it over his face and kept one hand on it while the other held in his regulator. Before he inserted it, he said, "Back soon with Kate," and patted the row-boat again.
Robbie the Row-Boat hardly paid attention. It was emailing another copy of itself to the Asimovist archive. It had a five-minute-old backup, but that wasn't the same Robbie that was willing to enter a human body. In those five minutes, he'd become a new person.

Robbie piloted the human-shell down and down. It could take care of the SCUBA niceties if he let it, and he did, so he watched with detachment as the idea of pinching his nose and blowing to equalize his eardrums spontaneously occurred to him at regular intervals as he descended the reef wall.
The confines of the human-shell were claustrophobic. He especially missed his wireless link. The dive-suit had one, lowband for underwater use, broadband for surface use. The human-shell had one, too, for transferring into and out of, but it wasn't under direct volitional control of the rider.
Down he sank, confused by the feeling of the water all around him, by the narrow visual light spectrum he could see. Cut off from the network and his telemetry, he felt like he was trapped. The reef shuddered and groaned, and made angry moans like whale-song.
He hadn't thought about how hard it would be to find Kate once he was in the water. With his surface telemetry, it had been easy to pinpoint her, a perfect outline of human tissue in the middle of the calcified branches of coral. Down here on the reef-wall, every chunk looked pretty much like the last.
The reef boomed more at him
