Morphogenesis of free neuromasts in the larvae of brown-marbled grouper epinephelus fuscoguttatus

Newly hatched larvae had one pair of free neuromasts behind the eyes. As the larvae grew, free neuromasts increased in number. Theapical surface of sensory epithelium widened and subsequentlyelongated. The number of sensory hair cells increased and thedirections of maximum sensitivity became both an...
