Sign in to saveAlso 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.

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.
==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.
