"With the recent functionally extinct declaration of the Baiji (Yangtze River Dolphin), it is now the world's most endangered cetacean."

Is this statement accurate? Its reference is from a 1995 publication (since which a lot could have happened), and the statement contradicts North Pacific Right Whale, of which the most recent revision currently asserts that the titular species is the most endangered marine mammal. --UberScienceNerd Talk Contributions 17:48, 3 August 2008 (UTC)

I agree that a 13 year old source is not definitive on which cetacean species is currrently most endangered. In fact, based on the way the sentence is worded, I suspect that the claim is OR, based on the vaquita being listed below the baiji in book, with the conclusion being drawn that the vaquita moved up into the most endangered spot with the extinction of the baiji. I'm going to hide the claim for now. -- Donald Albury 23:12, 3 August 2008 (UTC)

WP:CETA capitalisation discussion[edit]

"General references"[edit]

Please rework the "General references" section into a series of inline citations. "General references" sections such as this one can make it difficult to tell which claims are sourced and which ones are not. Chris (talk) 20:08, 5 November 2011 (UTC)

as far down as 30 or 50 meters?[edit]

In the "Distribution and habitat" section, it says that they rarely swim deeper than 30 m, but they are most often seen at 11 to 50 m. This appears to be somewhat contradictory; if they are rarely seen below 30 m, how can they go down to 50 m so often?

It says they are most often found in water 11 to 50 m deep, but that doesn't necessarily mean they always dive to the bottom wherever they are found. There's really no contradiction. WolfmanSF (talk) 05:49, 6 February 2017 (UTC)

Individual protection?[edit]

Given the number of vaquitas is now close to single digits, wouldn't it be feasible to have a Sea Shepherd ship following each individual vaquita around the clock, to prevent illegal fisherboats coming near one? If the scientist can count them, they must be able to find and track them somehow... Or would this cause to much stress on the vaquitas? --Roentgenium111 (talk) 14:52, 5 July 2018 (UTC)

This is really not something for the article, unless you are aware of a reliable source about such a proposal. To answer your question, vaquitas are usually solitary, so monitoring them would require twelve or more boats on the water simultaneously all the time, which would be a large logistical operation. It would also require that each vaquita be tracked at night, in fog, in storms, etc. The number of vaquitas is not an exact count; it is almost certainly based on vaquitas being seen in different areas during some period of time, and, with luck, some identifying mark (often scars) spotted by an observer. - Donald Albury 17:04, 5 July 2018 (UTC)
The vaquitas are not necessarily being taken directly by boats, they in some cases fall prey to nets that have been left during the night (to take totoaba) and then are retrieved days later (or in some cases maybe never retrieved). Getting rid of all the nets would save them, but that is not likely unless all boat traffic and fishing activities are continuously monitored. WolfmanSF (talk) 17:50, 5 July 2018 (UTC)
