Several individuals with developing radiolar crowns and variable number of thoracic segments (3–7) were found within tubes of adults, indicating intratubular direct larval development. In these offspring, radioles are rudimentary (as small, rounded protuberances or short, digitiform radioles without pinnules) and thorax is not completely formed (few chaetigers are present and the first three thoracic segments are narrower and shorter than rest of the body). Ripe males or hermaphrodites were not found in the hundreds of examined specimens, but packages of germ cells were observed in abdominal segments A1–A3 (
