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

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

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)


 * 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.
