Table S1 - High Prevalence of Proposed Müllerian Duct Remnant Cysts on the Spermatic Duct in Wild Eurasian Otters (Lutra lutra) from Sweden

Data on otters included in the study. Identification number, year of death, cause of death, total length (from nose to tip of the tail), weight, age group and locality data are given, as well as number of cysts on each individual. The otters were divided into three age groups according to their estimated age: juvenile (up to 5 months old), subadult (approximately 5 -18 months old) and adult (over 18 months old), based on the presence/absence of long bone growth plates, and in some cases also on the size of the testis and baculum. Some otters lack information on length and/or weight, most often due to severe damages in traffic. (DOCX)

本研究涉及的水獭相关数据包含以下内容：个体编号、死亡年份、死亡原因、全长（鼻尖至尾尖）、体重、年龄组、采样地点信息，以及每只个体的囊肿数量。本研究根据估算年龄将水獭划分为三个年龄组：幼崽（5月龄及以下）、亚成体（约5~18月龄）与成体（18月龄以上），划分依据为长骨生长板的有无，部分个体还辅以睾丸与阴茎骨的大小作为参考。部分水獭缺失全长和/或体重数据，此类情况多因遭遇严重交通事故所致。(DOCX)
