Here are some tasks awaiting attention:
Priority 1 (top)

Newt image[edit]

The cell looks like it's in metaphase. Info on cell cycle here. The original owner does say that the image is of early anaphase but not all the chromosomes are on the meiotic plate yet, meaning it's in late metaphase. I think my correction was right.

Temporal Range[edit]

Is there a reason that the temporal range of the animals is listed as starting at 670 Ma, but a higher clade, Holozoa, is listed as 610 Ma, which is _sooner_? Holozoa contains Animalia, so it should be older. 204.248.56.23 (talk) 00:29, 19 August 2015 (UTC)

The Internet and cats[edit]

Please swing by and help improve this new article! :D--Coin945 (talk) 03:30, 2 October 2015 (UTC)

Cat people and dog people[edit]

Please consider creating this proposed article on an extremely notable topic. (Sources are included).--Coin945 (talk) 15:30, 9 October 2015 (UTC)

Broken Taxobox[edit]

The entire top of the page was a mess; I think b/c of some error with the Taxonomy Box template. I commented out the Taxobox to fix the page temporarily. Can someone who knows how fix and restore the template? Thanks! Openflower (talk) 17:35, 17 November 2015 (UTC)

Ctenophores[edit]

This article seems to be showing support for the idea that ctenophores are the most basal metazoan. While the two papers that are sited do put this idea toward, it should be noted that most workers in this area do not support this idea. Specifically, the authors of the two papers have not taken into account long branch attraction as an explanation for the obtained tree topology. I think we should put forward the current consensus (that sponges are the most basal metazoans), while mentioning the basal ctenophore idea as a possibility, whilst also mentioning why it is unlikely. Gc12847 (talk) 14:55, 18 November 2015 (UTC)

I absolutely agree. Not only was this not settled science at the time of writing, but as of today, there's an important paper in PNAS challenging the "Ctenophore-first" hypothesis and upholding the traditional "sponge first" one: [1] [2]
Wikipedia needs to take a neutral point of view on this, just like any other issue where there's a genuine controversy or at least lack of consensus within the scientific community on a question. I say, go ahead and rewrite this if you're so inclined. Peter G Werner (talk) 07:15, 1 December 2015 (UTC)

Semiprotection? Why?[edit]

Why this article is semi-protected? I don't understand, I find absurd.--181.27.183.230 (talk) 23:21, 30 April 2016 (UTC)

Hi, it was semiprotected because of persistent vandalism. Are there any specific edits you'd like to make? I'd be happy to post them for you if you make them here. Intelligentsium 01:25, 1 May 2016 (UTC)

The article states that all animals are motile. I believe that sponges and corals are now considered to be animals, and they are sessile. — Preceding unsigned comment added by Philonous2 (talkcontribs) 14:29, 21 May 2016 (UTC)

All animals have motile phases at some point in their live. Sponges and corals both have motile laval stages. Gc12847 (talk) 15:35, 27 October 2016 (UTC)

Introduction[edit]

There is this sentence: These include molluscs (clams, oysters, octopuses, squid, snails) octopuses and squid are cephalopods why not writing These include molluscs (clams, cephalopods, snails) --Hamonv (talk) 08:51, 22 October 2016 (UTC)

From the article Mollusca: " Cephalopod molluscs, such as squid, cuttlefish and octopus, ..." --Vsmith (talk) 14:05, 22 October 2016 (UTC)

In the introduction, they should talk about how animals go through homeostasis and how it regulates their body temperture depending on the environment they live in. User: (andreabrisby) 19:47, 27 2016 (Andreabrisby (talk) 00:48, 28 October 2016 (UTC))

Use of 'developed' vs 'evolved'[edit]

In the sentence "The Myxozoa, microscopic parasites that were originally considered Protozoa, are now believed to have developed from within Cnidaria.[75]" the word 'developed' should be substituted by 'evolved'. Evolution is changes from generation to generation. Development is changes within a single individual throughout its lifetime. Grahamdane (talk) 21:17, 28 November 2016 (UTC)

Agreed. Yes check.svg Done Peter coxhead (talk) 21:29, 28 November 2016 (UTC)
