Dark spot surrounded by yellow ring on side of caudal peduncle, just ahead of upper part of caudal fin base (Ref. 26938).
深色的斑點在尾柄的側邊上被黃色的環包圍了, 在尾鰭基底的上半部之前正好。 (參考文獻 26938)
Facultative air-breathing (Ref. 126274); Adults inhabit shallow, mud-bottomed ditches, bays, salt marshes and other brackish-water environments; also crab burrows (Ref. 5723), moist leaf litter, decaying mangrove logs (Ref. 93034). Can withstand heavy pollution of fresh or salty waters and shares its biotope with Poecilia vivipara which is much more abundant (Ref. 35237). Usually found in water with low oxygen content (Ref. 7251). Either male or hermaphroditic, females don't seem to exist. Only about 5% of a population are born as males; after 3-4 years about 60% of the (self-fertilizing) hermaphrodites transform into secondary males by losing female structure and function. The proportion of males depends on the environmental temperature. Below 20°C, majority are males, above 25°C all are hermaphrodites (Ref. 35237). It is the only known naturally occurring, self-fertilizing vertebrate (Ref. 13056, 35237). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139).
棲息於淺灘，泥質底的溝渠，海灣，鹽濕地與其他的半淡鹹水環境; 螃蟹也掘洞穴。 (參考文獻 5723) 能用 胎花鱂〔Poecilia vivipara〕 抵抗生鮮魚肉或者鹹的水域重污染而且分享它的生存環境是更加豐富的.(參考文獻 35237) 通常發現於水具有低溶氧量.(參考文獻 7251) 或雄魚或雌雄同體的, 雌性似乎不存在。 只有大約 5% 的族群出生當雄性; 在 3-4 年大約 60% 的 (自我受精的) 雌雄同體藉由失去雌性的結構與功能轉換成次要的雄性之後。 雄性的比例仰賴環境的溫度。 下面 20 °C ，多數是雄性, 在 25 °C 之上全部是雌雄同體的.(參考文獻 35237) 它是已知唯一的自然地出現, 自我受精的脊椎動物.(參考文獻 13056,35237) 不是一個季節性的鱂科魚類。 在水族館非常難以維持。 (參考文獻 27139)

Eggs are sometimes fertilized internally by accident via close apposition of gonopores in otherwise oviparous fishes (Ref. 7471). Regarded as a self-fertilizing hermaphrodite (Ref. 6028, 245, 35237). Eggs are 1.6 mm in diameter. Sexes can be distinguished after 8 weeks (Ref. 35237).
