It is one of forty-four species from the minnow and carp family of Cyprinidae in these areas.〔(【引用サイトリンク】url=http://redpath-museum.mcgill.ca/Qbp/fish/specpages/northernredbellydace.htm )〕 ==Description== The Northern Redbelly Dace is a minnow about 55 mm long with two dusky, longitudinal stripes along its sides under an iridescent silver back. The top stripe often becomes broken into dots behind the dorsal fin. Small, almost invisible scales cover its body. The lower sides of its body are white, yellow, or silver. However during the breeding season, this area becomes brilliant red on the males. The females likewise exhibit a colorful, green ventral stripe. Helpful identifying characteristics are its long coiling intestines and the black peritoneum (lining of the body cavity). Its lateral line is incomplete and consists of 70 to 90 lateral line scales.〔("Northern Redbelly Dace" ). www.mass.gov/dfwele/dfw/nhesp/species_info/.../phoxinus_eos.pdf. Retrieved 5/1/2011.〕 The Northern Redbelly Dace has thin, flexible rays called "soft-rays". It possesses a pair of pectoral fins, pelvic fins in the ventral and abdominal positions, which all are white, yellow, or silver. No adipose fin can be found after the dorsal fin on its back. The caudal fin or tail fin is notched and homocercal. This means that the tail has two lobes that are symmetrical. 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「Northern redbelly dace」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.
