끄덕새우 (갑각강 : 생이하목 : 끄덕새우과)의 제1조에아 유생

Abstract

The first zoea of R. uritai is described in detail, based on laboratory-hatched material. The first zoea of R. uritai can be distinguished from that of R. conspiciocellus and R. durbanensis by the rostrum downwards, overreaching distal margin of the outer flagellum of the antenna, the endopod of the antenna with short seta as well as long plumose seta distally, and the scale of the antenna six-segmented. The shape of the telson can be a distinguishing character of the first zoea of Rhynchocinetes from that of Cinetorhynchus.

실험실에서 부화한 끄덕새우 (Rhynchocinetes uritaj) 의 제 1 조에아 유생을 상세히 기재하였다. 끄덕새우의 제1조에아 유생은 아래로 향한 이마뿔이 작은더듬이의 바깥채찍을 지나며 더듬이 안다리 끝에 긴 우상모와 짧은 강모가 있고 여섯마디로 된 더듬이비늘을 가져 동 속 R. conspiciocellus 와 R. durbanensis의 제1조에아 유생과 구별된다 끄덕새우속과 Cinetorhynchus 속의 제1조에아 유생은 꼬리마디의 모양으로 각각 구별할 수 있다.
