Sponges of Porifera have powerful regeneration capacity. Among them, the genus Tethya is a special group, which has differentiation in cortex and choanoderm. In this paper, the morphology of Tethya sp., and its wound-healing process were studied by removing specific part of some tissues, to understand the transformation of Tethya sp. and the role of different tissues in the healing process. The results showed that the main transformation in the wound-healing process is the cell rearrangement resulted by the cell migration from the unwounded to the wounded part, the cortex and choanoderm are vital to the survival of Tethya; while the spicule center is less importance in the wound-healing process.
