Speleonectidae
Speleonectidae is a family of remipede Remipedia is a class of blind crustaceans, closely related to hexapods, found in coastal aquifers which contain saline groundwater, with populations identified in almost every ocean basin so far explored, including in Australia, the Caribbean Se ...s in the order Nectiopoda. There are at least two genera and about seven described species in Speleonectidae. Genera These two genera and seven species belong to the family Speleonectidae: * '' Lasionectes'' Yager & Schram, 1986 ** '' Lasionectes entrichoma'' Yager & Schram, 1986 * '' Speleonectes'' Yager, 1981 ** '' Speleonectes epilimnius'' Yager & Carpenter, 1999 ** '' Speleonectes gironensis'' Yager, 1994 ** '' Speleonectes kakuki'' Daenekas, Iliffe, Yager & Koenemann, 2009 ** '' Speleonectes lucayensis'' Yager, 1981 ** '' Speleonectes minnsi'' Koenemann, Iliffe & van der Ham, 2003 ** '' Speleonectes tanumekes'' Koenemann, Iliffe & van der Ham, 2003 Several former ''Speleonectes'' species ...

Remipede
Remipedia is a class of blind crustaceans, closely related to hexapods, 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. 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, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morlockia Atlantida
''Morlockia atlantida'' is a species of eyeless crustacean in the order Nectiopoda. It was discovered in August 2009 in the Túnel de la Atlántida, the world's longest submarine lava tube on Lanzarote in the Canary Islands off the west coast of North Africa. Originally named ''Speleonectes atlantida'', it was transferred to genus '' Morlockia'' in 2012. Like other remipedes, the species is equipped with venomous fangs. Description ''Morlockia atlantida'' is approximately long. Like most other remipedes, the species lacks eyes and is hermaphroditic. Adapted to life in caves, the long antennae sprouting from its head and the presence of sensory hairs along its body allow the crustacean to feel its way along the dark tunnel. The species is equipped with venom-injecting fangs, a feature unique to class Remipedia among crustaceans. Discovery During a cave diving expedition to explore the Túnel de la Atlántida, the world's longest known submarine lava tube on Lanzarote in the ...
