This animal, Speleonectes tulumensis, is from a group of rare, blind, cave-dwelling crustaceans called "remipedes."

Remipedes and insects together are now shown to be a sister group to all the other crustacea including the crabs, shrimps, and lobsters. (Credit: Simon Richards)

Science Daily (Feb. 22, 2010) — Since the dawn of the biological sciences, humankind has struggled to comprehend the relationships among the major groups of "jointed-legged" animals -- the arthropods.

Their study is scheduled for publication in the journal Nature on Feb. 24.
