Talk:Secondarily aquatic tetrapods

	Evolutionary biology portal This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, and evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

What about sea otters? 75.83.150.164 (talk) 06:39, 12 July 2011 (UTC)[reply]

What about sea snakes? Speciate 23:45, 14 January 2007 (UTC)[reply]

Should be mentioned. Steve Dufour (talk) 05:16, 18 March 2009 (UTC)[reply]

Penguins too.Steve Dufour (talk) 14:27, 18 March 2009 (UTC)[reply]

Yes, we lack a few things here:

-Crocodilus Porosus, that might be on the way of becoming a 100% sea animal after a few millenia.

-Sea iguanas, same.

-Sea snakes, that mostly are 100% sea dwelling animals.

-And finally, Birds, especially Penguins, also on the way back.

Interesting to see that many of the earth-to-sea evolving species (Pinnipeds, Penguins, Polar bears etc.) are actually found on the poles of our planet... Any theories on that? --88.254.128.182 (talk) 04:36, 12 October 2010 (UTC)[reply]

Woops sorry on that, Crocodiles and Iguanas were already mentioned... But what about the ones "returning" to sea today as a way to differ them from the ancestors of Mosasaurs and so?

Is there a point to the list?

The article seems useful, but I'm not sure about the list. Since the subject apparently covers all partially or fully aquatic non-amphibian tetrapods, I suspect it is fully covered by a relatively small number of already existing lists that could be linked to here.

I see your point, but it's not so much a list, as the skeleton or outline of an actual article that needs to be fleshed out. Some of the statements seem trivia/list-like but it is just because more evolution detail is needed to connect them together; there are many sources that discuss aquatic tetrapods holistically in this way (e.g. [1], [2], [3]). However, they could be grouped more effectively, probably made into subheadings, with the main headings being Adaptations, Semi-aquatic tetrapods, Fully aquatic tetrapods; or alternatively, Marine reptiles, Marine mammals, Marine birds.

That being said, there is a List of semiaquatic tetrapods, but there is no matching list of fully aquatic or marine tetrapods. I would support the creation of a separate list article for that, but there should be a descriptive overview here in the Secondarily aquatic tetrapods article, elements of which can be drawn from Flipper (anatomy), Fin and flipper locomotion, Marine mammal and others.
