World's Greatest Islands ‘Island Arcs’ - wrong kind of "arc"

[prl]

I didn't know the episode title was wrong before I saw the episode - sorry. You may want to fix up the data anyway.

The episode title for World's Greatest Islands 'Island Arcs' (Nine/Nine HD 13:00 Sun 13 Jan) was actually 'Island Arks' - about how island isolation can generate unusual ecosystems and species that inhabit them. 'Island Arks' was the episode title used in the program.

I had wondered a bit about the episode title when I saw it because the previous episode was 'Island Archipelagos' and 'Island Arcs' sounded too similar.

Don't feel too bad, the authors of the episode's subtitles made the same mistake several times, too :)
