''Lepidocephalichthys thermalis'', known as the Common Spiny loach or the spotted loach, is a freshwater fish species restricted to India and Sri Lanka.〔http://www.iucnredlist.org/details/172360/0〕 They are found usually in quiet, flowing waters with a sandy substrate. ==Related species and diagnosis== Also endemic ''Lepidocephalichthys jonklaasi'' is found in Sri Lanka. Jayaram (1981) reports that at least six other species occur in the north-eastern part of India (Assam to Burma). Tilak & Hussain (1981) have written a review on the systematics of the Indian members of the genus. ''Lepidocephalichthys jonklaasi'' is distinguished from ''L. furcatus'', ''L. micropogon, L. manipurensis, and L. goalparensis'' by rounded/truncated (vs. forked) caudal fin, from ''L. irrorata and L. kranos'' by absence of scales on top of head, from ''L. guntea, L. hasselti, L. tomaculum, L. alkaia, and L. annandalei'' by broad regularly spaced dark bars (vs. reticulations, spots, or stripe) on caudal fin, from ''L. thermalis, L. arunachalensis, L. coromandelensis, and L. berdmorei'' by vertically elongated, dark spots on side that form irregular, thin bars (vs. round spots that sometimes form squares or thin stripe), and from ''L. lorentzi'' by thinner, more irregularly spaced dark side bars, dorsal-fin origin anterior (vs. posterior) to pelvic-fin origin, and larger size (to 45 vs. 33 mm SL), (Havird & Page 2010). The two Sri Lankan species ''L. jonklaasi'' and L.''thermalis'' are not very closely related. They are easily differentiated by body shape and proportions, colour pattern, and form of sexual dimorphism that is unique to ''L. jonklaasi''. Further, a mature adult ''L. jonklaasi'' is significantly longer than ''L. thermalis''. It is not easily confused with ''L. thermalis'' owing to its distinctive colour pattern and robust, tubular body. 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「Lepidocephalichthys thermalis」の詳細全文を読む スポンサード リンク
