The cirolanid isopod Cirolana harfordi is described as a scavenger and a predator that lives in the intertidal region. In order to understand the microanatomy of the mouthparts and the setae that allow this animal to handle and eat its food, a scanning electron microscopy study was conducted. C. harfordi displays a variety in the types of setae distributed on its mouthparts in a site-specific fashion, including complex setae placed on the medial edge of the maxilliped and maxilla. Terminal pores in some setae were found to contain a cupule, which is a hemispherical structure, housed in the concave recess of the pore, which demonstrates that the pore is more than merely a thinning of the cuticle as has been proposed. Future studies on setal morphology are needed for comparative microanatomy of cirolanid isopods.
描述食碎屑动物兼捕食者的潮间带豆形异尾虫为 Cirolana harfordi，为了理解该动物处理和进食食物的口器及刚毛的微观解剖结构，进行了扫描电子显微镜研究。Cirolana harfordi 口器上的刚毛在特定位置分布存在多种类型，包括放置在螯肢和大颚内侧缘的复杂刚毛。一些刚毛的末端孔中发现含有杯状结构，杯状结构位于孔的凹入凹陷中，这表明孔不仅仅是如之前所提出的那样是角质层的变薄，未来需要对刚毛形态进行比较研究，以了解豆形异尾虫的比较微观解剖学。
