簡短描述
型態特徵 | 形態測量圖
臀棘 1; 臀鰭軟條: 9 - 11; 脊椎骨: 30 - 31. Body pale, with long vertical stripes in both sexes, some over 2/3 body depth; perianal organ small, less than half length of pelvic disc; pelvic anterior membrane depth about half pelvic spine length in ventral midline; body with well spaced scales in single series along lateral midline, and otherwise naked except on caudal peduncle and side of anterior abdomen; typical D2 I/10-11; interorbit with two transverse rows of sensory papillae.
身體灰白的有長的垂直斑紋雄性與雌性都有, 約超過 2/3個體高; 肛門周圍的器官小的, 少於腹鰭體盤的一半長度; 在腹的中線中的腹鰭前面的薄膜深度大約一半的腹棘長度; 身體有在單一系列中有些間隔鱗片沿著側面的中線, 與不一樣地裸露的除了在尾梗上之外與前面腹部的側邊; 典型的 D 2個 I/10-11; 眼窩有兩個橫跨的列知覺的乳突。
With a mature female at 18 mm SL, this is the smallest European freshwater fish; 2.1 mm at hatching its larvae are the smallest free-living European vertebrates. Found in areas covered by aquatic vegetation, in reed stands; in sheltered bays down to 15 m (Ref. 59043); at the mouth of tributary streams and has been observed in small shoals near the surface, over open areas of gravel or stones (Ref. 26100). Feeds on invertebrates, mainly on cladocerans and larvae of mussel Dreissena polymorpha during the spawning season. Spawns after first winter, from February to May, with eggs (0.7 x 0.6 mm) deposited in a cavity (usually inside standing, broken reeds); these are cleaned and guarded by the male. A single nest may occupy up to 2000 eggs spawned by several females; with females spawning at least twice during the season. Eggs hatch in about a day, the larvae living on the surface layer, near shore, and after yolk absorption, live in deeper layers or near bottom, moving upward at night. Maximum known age is 21 months. Land reclamation, lake level fluctuations resulting to water abstraction and pollution threaten survival of this species (Ref. 59043).
成熟的母魚 18 mm SL, 這是最小的歐洲淡水魚。 發現在支流的嘴巴了。 曾經在小的淺灘接近水表面觀察, 在礫石或石頭的開放水域之上。 吃無脊椎動物。 從四月到五月產卵。 受到威脅的由於水資源減少與污染.(參考文獻 26100)
