Particularly abundant in coastal creeks and floodplains where it is supported by a certain salinity level. It is vulnerable to a trematode parasite which induces a characteristic cutaneous reaction. Reproduction in captivity has been successful (Ref. 12225). Maximum length questionable (Ref. 38376).
特别地丰富的在海岸的小溪与洪泛区中在哪里它被由一个特定的盐度支撑。 它是易受伤害的对引诱一个特殊的皮肤反应的一个吸虫寄生虫。 人工环境下的繁殖已经是成功的。 (参考文献 12225) 最大的长度可疑的.(参考文献 38376)
