不列颠哥伦比亚大学发现萨利什海两个新海蜘蛛物种

不列颠哥伦比亚大学研究人员在萨利什海发现了两个新的海蜘蛛物种，这是该地区一个世纪以来首次发现新物种1。研究团队由Cormac Toler-Scott领导，在浅水区（深度从0到约60英尺）采集样本，共鉴定出七种海蜘蛛，其中包括五个已知物种和两个新物种1。

两个新物种分别被命名为Callipallene pilosuspedes和Tanystylum kiixin1。其中Callipallene pilosuspedes体长约1厘米，具有三瓣嘴和感觉毛发的特征1；Tanystylum kiixin则以发现地附近的土著村庄命名1。研究人员利用扫描电子显微镜和DNA分析技术对这些物种进行了分类1。这项研究成果已发表在《Organisms Diversity & Evolution》期刊上1。

Researchers from the University of British Columbia have identified two previously unknown sea spider species in the Salish Sea, marking the first discovery of new sea spiders in the region in over a century 1. The findings, published in the journal Organisms Diversity & Evolution, were led by Cormac Toler-Scott and document seven sea spider species overall collected from the shallow waters of the Salish Sea, ranging from the surface to approximately 60 feet deep 1.

The two newly identified species represent distinct morphological adaptations. Callipallene pilosuspedes, measuring roughly one centimeter in length, is characterized by fine hair-like structures on its legs, a three-lobed mouth, and sensory hair projections 1. The second new species, Tanystylum kiixin, derives its name from an indigenous village near its discovery location and features legs covered with debris 1. Classification of both species was confirmed through scanning electron microscopy and DNA analysis 1. These discoveries were made alongside five previously known sea spider species found in the same survey area 1.
