The sea scorpion had heaved its broad, platelike prosoma out of the water; this crablike head-body was half a meter across. Behind the lozenge-shaped compound eyes was the creature’s long, tapering abdomen, plated in overlapping horizontal ridges. "It’s three meters long," Greta said as a servo delivered the first course. "Longer if you count the tailspike. A nice size for an invertebrate. Have some soup."
