I have made a couple of adjustments to the article. Overall, the article is well-written and accurate. It is broad in coverage. It would benefit from more discussion about the differences between Indian Ocean and Pacific Ocean populations. (Are they distinct subspecies?) The article is neutral, stable and nicely illustrated.
I am awarding GA status. Thanks and congratulations to all editors, especially Yzx. Axl ¤ [Talk] 18:43, 25 May 2009 (UTC)
