On April 10, 2015, three individuals of an undescribed species of ctenophore were observed moving just above the seafloor in the Arecibo Amphitheater inside the Guajataca Canyon, north-northwest of Puerto Rico at a depth of approximately 3,900 m. The ctenophore is distinctive; having two prominent tentacle arms, a body that is rectangular when observed laterally along the tentacular plane, and rounded when observed laterally along the stomodeal plane. The tentacle arms each give rise to an extensible tentacle bearing short tentilla of uniform length and distribution. One ctenophore appeared to be anchored to the seafloor by its two long flexible tentacles, as well as by two filaments exiting its oral end. The overall form of the ctenophore suggests classification within the problematic, non-monophyletic order Cydippida, but the robust tentacle arms are more reminiscent of benthic species of Platyctenida, particularly those of families Lyroctenidae and Ctenoplanidae. Whereas most platyctenid ctenophores do not possess ctene rows in their adult forms, features that are possessed by the new species described herein, species of Ctenoplanidae retain comb rows as adults and are capable of limited swimming. The species described herein is easily distinguishable from all other known species of Ctenophora and may trace its origin to a lineage diverging near the origin of Platyctenida.

アメリカ海洋大気庁 #NOAA により発見された深海性クシクラゲの新種。触手をアンカーにして海底からバルーンのように浮遊する生態も興味深いですが…新種記載の方法も見物です。 生体が採集できず標本が作れなかった事から、映像がタイプになっています。Holotype video! https://t.co/R9Ko1YKgDw https://t.co/fSwqU3TbaE
これが原典か。 この深海性有櫛動物の新種記載、ホロタイプとパラタイプともにスミソニアン国立自然史博物館に登録された動画資料に基づいている。 動画資料での記載って前例あるのだろうか……?(私は初見で驚いた) 奇しくも?記載媒体は日本プランクトン学会の英文誌。 https://t.co/Gw3IYFui9p
