Dark spot surrounded by yellow ring on side of caudal peduncle, just ahead of upper part of caudal fin base (Ref. 26938).
深色的斑点在尾柄的侧边上被黄色的环包围了, 在尾鳍基底的上半部之前正好。 (参考文献 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).
栖息于浅滩，泥质底的沟渠，海湾，盐湿地与其他的半淡咸水环境; 螃蟹也掘洞穴。 (参考文献 5723) 能用 胎花鱂［Poecilia vivipara］ 抵抗生鲜鱼肉或者咸的水域重污染而且分享它的生存环境是更加丰富的.(参考文献 35237) 通常发现于水具有低溶氧量.(参考文献 7251) 或雄鱼或雌雄同体的, 雌性似乎不存在。 只有大约 5% 的族群出生当雄性; 在 3-4 年大约 60% 的 (自我受精的) 雌雄同体藉由失去雌性的结构与功能转换成次要的雄性之后。 雄性的比例仰赖环境的温度。 下面 20 °C ，多数是雄性, 在 25 °C 之上全部是雌雄同体的.(参考文献 35237) 它是已知唯一的自然地出现, 自我受精的脊椎动物.(参考文献 13056,35237) 不是一个季节性的鱂科鱼类。 在水族馆非常难以维持。 (参考文献 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).
