"Lactrodectus mactans" is a variety of black widow spider found only in southern Chile. The spider's bite can be fatal but it's venom contains unique properties that some scientists find irresistible.¡®¶óÆ®·Îµ¦Åõ½º ¸·Åº½º(Lactrodectus mactans¡¤ÀÌÇÏ °ËÀºµ¶°Å¹Ì)¡¯´Â °ËÀº°úºÎ°Å¹Ì(black widow spider)ÀÇ ÇÑ Á¾·ù·Î Ä¥·¹ ³²ºÎ¿¡¼­¸¸ ¹ß°ßµÈ´Ù.
