异海星（Allostichaster capensis，Perrier，1875）是一种生活在南大西洋海岸的裂产海星。在巴塔哥尼亚海岸，它显示了一年一次的有性和无性生殖周期。分裂在南方的夏季（11月至次年1月）最为频繁，而臂再生则在一年中的其余时间进行。在这篇文章中，身体舱室的生化组成的季节性变化，这裂产海星的人口在巴伊亚凯泽，Golfo努埃沃，丘布特，阿根廷，从2000年6月至2002年5月。在年周期中，性腺和幽门盲囊指数之间的反比关系表明营养转移。生化分析表明，只有脂质转运从幽门盲囊性腺在配子发生的开始。Rev.Biol.Trop.56（增刊3）：351-360。Epub 2009年1月5日。
Allostichaster capensis (Perrier, 1875) (= inaequalis) is a fissiparous starfish inhabiting the South Atlantic Ocean coasts. On the Patagonian coast, it displays an annual sexual and asexual reproductive cycle. Fission is most frequent during the austral summer (November-January) and arm regeneration takes place during the rest of the year. In this article, seasonal changes in biochemical composition of body compartments are presented for a population of this fissiparous starfish in Bahia Kaiser, Golfo Nuevo, Chubut, Argentina, from June 2000 to May 2002. During the annual cycle, an inverse relationship between gonad and pyloric caeca indices suggests nutrient transfer. Biochemical analysis revealed that only lipids are translocated from pyloric caeca to gonads at the beginning of gametogenesis. Rev. Biol. Trop. 56 (Suppl. 3): 351-360. Epub 2009 January 05.
