Hemiscylliidae (Bamboo sharks)
Etymology: Hemiscyllium: hemi-, from hemisys (Gr.), half, presumably referring to similarity and/ or close affinity to Scyllium (=Scyliorhinus, now in Scyliorhinidae) and/or Chiloscyllium; skylion, Greek for dogfish or small shark (See ETYFish); freycineti: In honor of French Navy officer Louis de Freycinet (1779-1841), commander of the expedition during which holotype was collected (See ETYFish).
Eponymy: Captain Louis Claude de Saules de Freycinet (1779–1841) was a French navigator who was involved in mapping the Western Australian coast (1803). [...] (Ref. 128868), visit book page.
