| Abstract: | Morphological characters of Odontobutis obscurus in Huaihe river were studied and its taxonomic status was also discussed.In countable characters,there are Ⅶ,Ⅰ-9~10 dorsal fin-rays,14~15 caudal fin-rays,Ⅰ-7~8 anal fin-rays,Ⅰ-5 ventral fin-rays,14~15 pectoral fin-rays,36~41 longitudinal scales,14~18 transverse scales,9~11 gill rakes,28~29 vertebras.In measurable characters,total length is(1.23±0.03)times of body length;body length is(3.82±0.45)times of body height,(3.08±0.49)times of head length,(5.19±0.54)times of caudal peduncle length,(1.86±0.52)times of digestive tube length,(6.99±2.86)times of intestines length.Head length is(2.94±0.42)times of snout length,(6.09±0.87)times of eye diameter,(3.86±0.61)times of the distance between eyes,(1.94±0.27)times of mouth width.Body height is(0.96±0.11)times of body width.Caudal peduncle length is(1.66±0.18)times of caudle peduncle height. |
