The trainer says that in the six years since Lucky joined the park, no one has never seen her engage in mating behavior, and she isn't much for playing with the others. Perhaps this is because she is a Japanese gilli dolphin, making it harder for her to get along with the others, which are southern bottlenose.
訓練師說，招財入園六年多，大家從來沒有觀察到它有交配的行為，也不太和其他海豚玩在一起，可能是因為它的品種是日本吉氏海豚，和其他南方瓶鼻海豚相處，有所隔閡。
