溫德米爾水母(學名:Windermeria)又名溫德米爾蟲,是前分節動物門雙側水母綱底下的一個物種。在最一開始只發現了一個編號為GSC 102373的化石標本,[2][3]在那之後也陸陸續續地發現了其他化石,可能是親戚關係關係的管水母蟲屬都是在加拿大英屬哥倫比亞省塞奎布魯克河北邊的藍花地層。[4][5][6][7][8][9]與伊沃維克蟲屬一樣都生活在大約5億5千萬年到5億4千3百萬年[1][10],也都是雙側水母綱底下的物種。[1]溫德米爾水母的是以溫德米爾湖(Windermere)命名的,因為此物種的化石就是在溫德米爾湖發現的。種小名的「aitkeni」是為了感謝詹姆斯·D·艾特肯(James D. Aitken)對藍花地層的地理貢獻。[2]溫德米爾水母長1.64公分,寬0.79公分,大致上是橢圓形,且兩邊大約平行,身體的頭尾兩端是圓形的。 而且身體有分節,之中會有溝槽。[2]溫德米爾水母是生活在淺水裏,與其他當地的雙側水母類不一樣,且用匍匐的向前移動。[3][4]
