- 論文の詳細を見る
An intersexual specimen of the sea spider, Cilunculus armatus, having female and male characteristics together with some intermediate ones was collected from Sagami Bay. Eggs are seen through the cuticle of each femoral segment of walking legs. At the same time, cement gland, peculiar to male, is also found on the same segment of each walking leg, but somewhat atrophied and distally shifted. Genital pore opening on the second coxal segment of each walking leg as seen in female is of intermediate size between the sizes of both sexes. Oviger is intermediate in size and shape, and the number and distributional pattern of ovigerous compound spines are also intermediate.
