Research Abstract |
The planula larva of acroporid coral is arrested in development, and starts metamorphosis after receiving environmental signals from the substrate to settle on. In this study, experiments using dissected larvae revealed that responsiveness to a metamorphosis-inducing hormone is restricted within the aboral1/3region while responsiveness to external metamorphic cues is distributed along the whole body. These results suggest downstream internal signals secreted from aboral tissues to achieve metamorphic reactions throughout the whole body following the hormone, and an alternative metamorphic signaling cascade beside the hormone in the oral region.
