Systematics and phylogeny

Amphiura is a large genus that is currently divided into the following six subgenera: Amphioplus, Amphiura, Fellaria, Ophionema, Ophiopelte and Ophiopeltis. The once used subgenus Acrocnida has been elevated to a genus rank. Fossil record of the genus date back to Turonian (Amphiura plana).[1]

Species

Extant species include:[2][3]

gollark: What if we make it so that proposals are *automatically* passed when the rules state they should be, and directly patch the code of the bot?
gollark: What if we make it so that votes are done by allowing each player to set a few cells of the initial state to a complex cellular automaton, and then the output of that after a few billion steps is parsed into the result of the vote?
gollark: Wait, what if we treat passing/failing proposals as a 1D cellular automaton?
gollark: Oh, and also, pass proposal but translated to Latin, pass proposal 3 days ago, pass proposal *in* 6 days, and randomly reassign all rule numbers.
gollark: It may take a little while to do the necessary votes, but it would be ENTIRELY worth it.
