Talk:East Asian finless porpoise

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Narrow-ridged finless porpoise. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

• Attempted to fix sourcing for http://www.wwfchina.org/english/loca.php?loca=412

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Mixed-up sources and questionable info

Over half of the references here refer to the other form of finless porpoise. Likewise, the article on that taxon mixes up sources/taxa, as does the article on porpoises in general.

This taxon, if it truly is an independent species, is also recorded for Japan, where the population is doing reasonable and is not in danger of extinction as of 2013. The original 2011 paper splitting the taxa also classifies the Japanese populations as this species, although as a separate subspecies (a 2013 Japanese paper classifies them as the nominate form of Neophocaena asiaeorientalis). The Korean populations also appear to be classified as the nominate form of this taxon.

In the section on distribution, the sourced text contradicts the unsourced paragraph before it.

The description section mixes the descriptions of both taxa with each other, but is almost completely about N. phocaenoides judging by the references. Likewise, the conservation and captivity sections confuse taxa. The stuff about decline is mostly about the nominate N. asiaeorientalis in the Inland Sea of Japan, although there are some unreferenced things added in there. The WWF stuff estimating decline is working with old population estimates that are probably too high (as theirs may be too low), not sure any of that data is trustworthy.

The distribution map is also questionable, the range of this taxon is far too far upriver, and the map is missing ranges in Indonesia compared to other maps in the sources.

Some info about taxonomic history, dates recognised, and which authorities recognise whichever taxonomic scheme in which geographic regions would be helpful. Also the purported morphological differences with the original taxon and their significance seems pertinent, as a reappraisal of the known varietal differences in morphology seems the basis for raising this taxon to species level in the 2011 paper. 86.83.56.115 (talk) 21:36, 13 November 2018 (UTC)

Move discussion in progress

There is a move discussion in progress on Talk:Neophocaena which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 10:07, 10 September 2021 (UTC)
