布氏針鼴蝦（學名：Echidnacaris briggsi）是針鼴蝦屬（學名：Echidnacaris）的一個種，也是模式種。^[1]原本是位在奇蝦屬（學名：Anomalocaris ）的布氏＂奇蝦＂（學名： "Anomalocaris" briggsi），之後對於針鼴蝦的系統發生學證明了針鼴蝦並不是奇蝦，而是獨立一個屬。^[1]針鼴蝦是除了奇蝦屬的戴氏奇蝦（Anomalocaris daleyae）唯一一個分佈在澳洲的放射齒目動物。^[1]^[2]^[3]^[4]^[5]

命名

原本針鼴蝦被克里斯多福·內丁（Christopher Nedin）於1995年發表的，當時被命名為布氏奇蝦（ Anomalocaris briggsi）^[6]，直到發表十幾年後因被懷疑是否為奇蝦屬，到2023年，針鼴蝦才重新歸類為新的屬。針鼴蝦的名字是以生活在澳洲的針鼴俗名－echidna，因為針鼴蝦附肢上有許多的小刺；caris是拉丁语的螃蟹，是恐蝦綱的常用作學名的字尾。^[1]
