| Outline of Final Research Achievements |
Ligia exotica repeateadly molt and every time molt it increase body size.To clarify a degree of adhesion dirty things as a factor of instability in the water absorption, we analyzed electron scanning microscope image. As a result, there were found many stains on the cuticular protrusions of just before the molting compared to immediately after the molting.
Besides, it was revealed that the larvae of L. exotica also has a water-absorbing structure similar to the adult. Since the larvae of L. exotica have only the six pairs appendage, they have been considered to have no cuticular protrusions for water absorption. We demonstrated the presence of similar structure to the fifth and sixth pereiopods of larvae in this image analysis.
