They are found on the bodies of mud shrimp (a.k.a. ghost shrimp) of the family Callianassidae, or from water collected from mud shrimp burrows. ==Description== ''C. dissimile'' is bright red with the deepest color along the margins of the segments. Pigmented areas often form dense irregular masses on either side of the gut. After several weeks in the laboratory the intensity of the color begins to decrease. The red pigmentation was observed in the naupliar, juvenile, and adult stages.〔Hayes, Howard J. (1984). Biology of ''Clausidium dissimile'': an epizoic copepod. M.Sc. Thesis, University of West Florida, Pensacola, Florida, U.S.A.〕 The female is short, broad and strongly flattened. It does not have visible eyes. The antennae are not nonprehensile. As characteristic of the genus, the endopods of the first four pairs of legs have sucking disks and the endopod of the first pair of legs has a distinct large flattened plate on the inner margin. Bright orange egg strings may be attached to the genital segment on the left and right sides. The eggs are large and spherical, 25 or 30 in each string. The total length is approximately 1.25 to 1.5 mm and the cephalothorax width is approximately 1 mm.〔〔Wilson, Charles B. (1932). The copepods of the Woods Hole region, Massachusetts. Bulletin of the United States National Museum 158: 1-165.〕 The adult male is much smaller than the female. The total length is approximately 0.6 to 0.7 mm and the cephalothorax width is approximately 0.30 mm. It is elongate and slender with appendages like those of the female. It is usually found firmly grasping the anal segment of the female. Besides its size, the chief differences are the maxillipeds and the first pair of legs, both of which are used to grasp the female.〔〔 The males begin pairing with the juvenile copepodid IV and V stage females.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Clausidium dissimile」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
