Color legend: orange, tentacle cords and nerves; green, laterofrontal nerve; pink, abfrontal nerve; purple, ganglion; cyan, circum-oral nerve ring; blue, outer nerve ring; white, oral serotonin-like immunoreactive perikarya; yellow, frontal nerve; grey, lateroabfrontal nerve; red, peritoneal neurites.
