Females of the maldanid polychaete Axiothella mucosa attach gelatinous egg masses to the surface openings of their vertical tubes. This study assessed the risks to the embryos due to environmental stresses. In Florida, embryonic development takes 7-8 d, after which the embryos crawl free from the egg mass and assume a benthic existence. Contrary to earlier suggestions, diatoms growing within and on the egg masses do not contribute significantly to embryonic nutrition. By marking cohorts of egg masses , it was shown that most egg masses become detached from the parental tube before natural release of the juveniles. A caging experiment established that water currents, rather than predators or other biological disturbances, are the cause of detachment.
