The story of the word

The name records a split in the legs: one set points forward for walking and grasping, another backward for swimming and springing. That is the direct contrast with the isopod, whose legs are all alike, and both names were coined in the same wave of early nineteenth-century crustacean classification. ἀμφί also encircles the amphitheatre, seating on both sides, and the amphibian, at home in both.
