鱗南乳魚科 (Salamanderfishes)
Etymology: Lepidogalaxias: Greek,lepis, lepidos = scale + Greek, galaxias, ou = a kind of fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態學
; 淡水 居於水底的; pH range: 3.8 - 4.5; dH range: 5 - ?; 非遷移的. 溫帶; 17°C - 26°C (Ref. 36498); 34°S - 35°S
Oceania: endemic to Western Australia in seasonal pools between the Blackwood and Kent rivers.
大洋洲: 在 Blackwood 與肯特河之間的季節性的水池中的西澳大利亞的特有種。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 4.3 range ? - ? cm
Max length : 7.4 cm SL 雄魚/尚未辨別雌雄; (Ref. 44894); 6.7 cm TL (female); common length : 4.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 5259)
Facultative air-breathing (Ref. 126274); Occurs in shallow streams, drains and temporary pools in generally acidic water around pH 4. Water typically is tea-coloured (Ref. 44894). Feeds mainly on aquatic insect larvae and small crustaceans. Spawn: late winter, early spring; internal fertilization (male with modified anal fin); female laying about 100 eggs. Rapid growth of hatchlings (reaching 2.5 cm by summer). Life cycle may be limited to 12 months. Young fish aestivates in pear-shaped burrow in mud until water returns in autumn. They have no accessory respiratory structures and cannot withstand low oxygen situations (Ref. 36499). About 25-30% of the population attains sexual maturity at the end of the first year. The breeding season coincides with heavy rains between late May and August. The lifespan typically lasts three years, but some fish persist for up to five years (Ref. 44894).
在酸鹼度 4 附近的通常酸性水域中出現於淺的溪流，排水溝與暫時的水池。 主要吃水生的昆蟲幼生與小型甲殼動物。 產卵: 冬季末, 初春; 體內受精;(雄魚有變異的臀鰭) 母魚產下大約 100個卵。 人工孵化出之魚苗的迅速成長.(在夏天之前達到 2.5 公分) 生命周期可能被僅限於 12個月。 幼魚直到水回返秋天時在泥中的珠狀穴中夏眠。 他們沒有附屬呼吸結構而且不能夠抵抗溶氧量低的情形。 (參考文獻 36499)
Internal fertilization is facilitated by the modified anal fin of the male. Female deposits about 100 eggs in the shallows.大洋洲: 在 Blackwood 與肯特河之間的季節性的水池中的西澳大利亞的特有種。
