초록
In this study, we report for the first time a hybridization between Caretta caretta andChelonia mydas in South Korea. On 7th May 2012, a sea turtle (Jeju sea turtle 01, JST01) was foundin the east coast of Jeju Island, South Korea. The morphological characteristics of JST01 werecompared with those of C. caretta and C. mydas that were frequently observed in Korean Seas. Interestingly, JST01 showed similar morphological characters such as body color, appearance ofcarapace, shape of upper beak, serration on marginal scute, and two claws with those of C. caretta. On the other hand, JST01 showed also similar patterns in several characteristics including thenumbers of marginal, inframarginal and costal scute, smooth carapace without keel, no contactbetween costal scute and nuchal scute with those of C. mydas. From these results, we suggest thatJST01 is one of hybrid animals bred between C. caretta and C. mydas, because JST01 has speciesspecificcharacters from both species. We anticipate that our study would be useful and have significantimpact onto study inter-specific hybridization in the groups of sea turtle.
