藤壶引起了许多博物学家的注意，并且经常在污物群落中占据主导地位。 Balanus amphitrite，是一种浅水橡子藤壶，能够栖息在从上海到潮下层的广阔区域，并作为表生物。它的生存和成功建立当地种群的潜力得到了各种生理适应和幼虫感官知觉的认可。该物种的幼虫生命周期有浮游营养无节幼体和非食性幼体阶段。无节幼体能量对鲤鱼幼虫探索表面定居的能力以及幼体的招募成功率有影响。藤壶中最完整的神经系统是在鲤鱼幼虫中建立的。尽管人们对它们的沉降和变态进行了大量的研究，但对于沉降和变态的嗅觉、光和听觉感觉机制知之甚少，需要进一步关注。了解藤壶最敏感的生命阶段对潮间带栖息地环境变化的反应也可以作为了解气候变化对物种分布影响的重要模型。 (C) 2010 Elsevier B.V. 保留所有权利。
Barnacles have drawn the attention of many naturalists and often dominate fouling communities. Balanus amphitrite, is a shallow water acorn barnacle capable of inhabiting expanses from supralittoral to subtidal levels, and as an epibiont. Its potential to survive and successfully establish local population is endorsed by various physiological adaptations and larval sensory perceptions. The larval life cycle of this species has both planktrotrophic naupliar and non-feeding cyprid stages. The naupliar energetics has a bearing on the capabilities of cypris larvae to explore surfaces for settlement and also the recruitment success of juveniles. The most complete nervous system in the barnacles is established in the cypris larva. Although there has been considerable research with reference to their settlement and metamorphosis, not much is known about the olfactory, photo and auditory sensory mechanisms with respect to settlement and metamorphosis, which need further attention. Understanding the response of most sensitive life stages of barnacles to environmental changes in intertidal habitats can also serve as important models for understanding the effect of climate change on species distribution.
