Abstract

Since a new (unrecorded) species was reported in 2016, a total of four sea snake species are currently listed in Korean waters. Although the possibility of year-round inhabitation of sea snakes in Korean waters has increased due to climate change, the related studies are scarce because of the lack of human resources and available equipment. We placed posters and banners requesting voluntary information on sea snakes in coastal regions and Jeju Island to obtain information on sea snake distributions in the coasts of South Korea and possible specimens through volunteer activities. As a result, we received total 45 reliable reports, including photographs or video, between March 2013 and December 2016. Eighteen reports on three sea snake species and thirteen capture cases of two species were submitted from Jeju Island and southern coastal regions of Korea mostly between August and November. There were twenty-seven false reports including seven cases of terrestrial snakes, eighteen fishes, and one each of invertebrate and inanimate material. Based on the results, we proposed the effective way of sea snake surveys using volunteers.

2016년에 1종이 추가로 보고되어, 현재 한국 연안에는 총 4종의 바다뱀이 분포하고 있다. 기후변화 등으로 한국 연안에 바다뱀의 년 중 서식 가능성이 높아지고 있으나 인적, 물적 한계로 인하여 관련연구가 미비한 상태이다. 국내 연안 내 바다뱀 분포에 대한 정보 및 샘플을 시민의 활동을 통해 확보하기 위하여 한반도의 해안지역과 제주도에 제보를 권하는 바다뱀 포스터와 현수막을 게시하고 제보를 접수하였다. 연구수행결과 2013년 3월부터 2016년 12월 사이 45건의 신뢰성 있는 제보가 접수되었다. 바다뱀 제보는 18건으로 주로 제주도와 남해안에서 접수되었으며, 시기적으로는 8-11월 사이가 많았다. 총 3종 18건의 바다뱀 분포정보와 2종 13개체의 포획이 가능하였다. 바다뱀의 오제보는 27건이었는데, 육지뱀이 7건, 어류가 18건, 무척추동물과 사물이 각 1건이었다. 자료를 바탕으로 시민을 활용한 효율적 바다뱀 조사방법에 대한 제언을 하였다.
