I don't care about the low resolution of the image. It is enough for DYK.

Swimming porpoises

• ... that porpoises (pictured) are known to teach, learn, cooperate, scheme, and grieve?

• ALT1:... that the neocortex of many species of porpoises (pictured) is home to elongated spindle neurons that, prior to 2007, were known only in hominids?

Improved to Good Article status by Dunkleosteus77 (talk). Nominated by Oceanh (talk) at 01:08, 12 December 2015 (UTC).

• Article was promoted to GA, nominated within due time. Long enough with more than 22,000 characters. Anyway, close paraphrasing can be seen by this tool as of now. Some text in fishing section is copied from this source. 1 or 2 lines are acceptable but here one para is copied. That should be fixed. Also I can't see hooks are mentioned in article. Image is in public domain. QPQ done. --Human3015^TALK  09:34, 9 January 2016 (UTC)

• Thank you for the review, and for finding the close paraphrasing. This should be rewritten. Since the article is a GA, I will let those who have worked with the article have a chance to fix this; if that should take too long time, I will see if I am able to rewrite the paragraph.

How about using a characteristic more unique to porpoises, because spindle neurons are found in all cetaceans including dolphins and whales, such as "ALT2... that porpoises (pictured) were one of the most accessible species for early cetologists, because it could be seen very close to land, inhabiting shallow coastal areas?" On to the whole plagiarism problem, there was an editor some while back that added a lot of (what looked like) plagiarized material, and I thought I had reverted all of their edits. I'll sort that out now. Dunkleosteus77 ^{(push to talk)} 17:24, 9 January 2016 (UTC)

• Issue of plagiarism has been fixed. I have not seen original hook and ALT1 is written in article. So I have stricken it. ALT2 is interesting enough and written in article and sourced. Good to go.--Human3015^{Let It Go}  07:24, 10 January 2016 (UTC)

• I came by looking to promote this, but found that the image is of very low resolution. I feel this is a great candidate for the main hook of DYK?, but wanted to see if we can do better on the photo. There's plenty to choose from at Commons:Category:Phocoena (File:Daan Close Up.PNG being my favourite, but perhaps not overly factual). I'll see if the nominator has any thoughts, before promoting.
