Examples of amphioxus in a Sentence
Word History
borrowed from New Latin, genus name, from Greek amphi- amphi- + oxýs "sharp, keen" — more at oxygen
Note: The genus name Amphioxus was introduced by the English naturalist and bookseller William Yarrell (1784-1856) in A History of British Fishes, vol. 2 (London, 1836), pp. 468-72. The name alludes to the shape of the animal: "both ends pointed," as noted under "generic characters." Yarrell was unaware that the Italian zoologist Gabriele Costa had named the same genus Branchiostoma two years earlier (in Cenni zoologici, ossia descrizione sommaria delle specie nuove di animali, Naples, 1834, p. 49); by rules of taxonomy, the name Branchiostoma hence has priority over Amphioxus.
1837, in the meaning defined above
