Remipedia
Also known as remipede
Remipedia is a class of blind crustacean-like animals, closely related to hexapods. They are found in coastal aquifers which contain saline groundwater, with populations identified in almost every ocean basin so far explored, including in Australia, the Caribbean Sea, and the Atlantic Ocean. The first described remipede was the fossil Tesnusocaris goldichi (Lower Pennsylvanian). Since 1979, at least seventeen living species have been identified in subtropical regions around the world.

槳足綱(學名Remipedia)是分布於濱海地下含水層中的甲殼亞門動物，不具視力，族群遍布在目前已知的海盆，如加勒比海、大西洋、澳洲海域，最早發現的槳足綱為賓夕法尼亞紀的化石，不過自1979年已在新熱帶界發現17種現存槳足綱動物。 槳足綱的分佈：(A)加勒比海(B)加那利群島(C)西澳州。

==Description== Remipedes are long and comprise a head and an elongate trunk of up to thirty-two similar body segments. Pigmentation and eyes are absent. Biramous swimming appendages are laterally present on each segment. The animals swim on their backs and are generally slow-moving. They are the only known venomous crustaceans (excluding hexopods), and have fangs connected to secretory glands, which inject a combination of digestive enzymes and venom into their prey, but they also feed through filter feeding. Being hermaphrodites, the female pore is located on the seventh trunk segment and the male pore on the fourteenth.
