Abstract

Grafting experiments with newly settled larvae and with adult colonies of Pocillopora damicornis were performed. When pairs of newly settled larvae released from different colonies were kept in contact, they fused to form an aggregated colony. Even newly settled larvae derived from colonies belonging to different color morphs fused with each other and no sign of allogeneic rejection was observed. However, when branches of adult colonies belonging to different color morphs were kept in contact, they did not fuse. Fusion was observed only when branches derived from the same colony were paired. The present results suggest that juvenile corals lack the functional histocompatibility system as shown by adult colonies.
