Looks good. Just a few minor things need to be addressed for it to meet the GA criteria. Thebiguglyalien (talk) 19:53, 18 April 2023 (UTC)[reply]
Criteria 1 and 3 are now met. All that needs to be addressed is criterion 2 with the one text-source integrity comment and some of the close paraphrasing (at least the one about Nucella lamellosa). Thebiguglyalien (talk) 23:26, 20 April 2023 (UTC)[reply]
@Thebiguglyalien That should be everything, please let me know if there's anything else. Thanks again for doing this. 🏵️Etrius ( Us) 15:22, 22 April 2023 (UTC)[reply]
Well-written
I did a few minor copyedits, feel free to review or change them.
Overall, some of the prose feels a little choppy. It's not a GA issue, but it's something to watch out for.
provide keen vision – This feels imprecise/unscientific. What's the benefit of outward angling?
Done, cut. The sentence implies causation but in reality these were meant to be two separate thoughts. 🏵️Etrius ( Us) 21:10, 20 April 2023 (UTC)[reply]
Their scavenging is considered an important factor in keeping beaches clean – Considered by whom? Why?
Slightly Reworded. The source only states: They contribute greatly to keeping the beaches clean by scavenging. 🏵️Etrius ( Us) 21:10, 20 April 2023 (UTC)[reply]
On later review I just cut this entirely. 🏵️Etrius ( Us) 21:11, 20 April 2023 (UTC)[reply]
and will employ chemical cues to avoid the crabs – What are "chemical cues" in this context?
This is more of a style choice, but I would combine all of the facts about Carcinonemertes epialti into a single sentence and cite it to both Cowles and Hiebert. This keeps all the info organized and lowers the chance of close paraphrasing. Something to the effect of "Like other species of the Hemigrapsus and Pachygrapsus genuses, H. nudus' eggs are vulnerable to parasitization by Carcinonemertes epialti".
Sourcing is consistent and most sources seem generally reliable. What makes NW Marine Life reliable?
NW Marine is a database of species in the NW coast of the US. I've cut the source since it only sites one small factoid.
Spotchecks:
Cowles. Walla Walla Uni. – Checked all 11 uses:
The source says that the purple shore crab doesn't have abundant setae on the legs, while the article says that they lack setae.
Done Added additional citation
The purple shore crab is an osmoregulator, thus it can tolerate hyper-osmotic and hypo-osmotic environments. – This is a fairly basic fact, but watch for close paraphrasing.
Nucella lamellosa has been documented to be attracted to the scent of H. nudus but is not a known predator. – Close paraphrasing.
Done Reworded 🏵️Etrius ( Us) 15:18, 22 April 2023 (UTC)[reply]
Does this source support that this species is most commonly found sheltering under rocks and in seaweed within the inter-tidal and sub-tidal regions?
Done Additional citations added
WoRMS – Good.
Hiebert (2015) – Checked all 17 uses:
Males will often fight when disturbed while females will autotomize. – Another that feels like close paraphrasing but is also a simple fact.
Done Slightly reworded for posterity's sake
Mcgaw (2003) – Checked all three uses:
One of the temperatures had a typo, but I fixed it.
Broad in its coverage
Do purple shore crabs have any significant interactions with humans? Are they farmed? Are there any conservation efforts surrounding them? Are there any environmental effects that are caused by or impact these crabs in particular (besides their scavenging)?
The only source I can find on this is Northern Bush Craft, I'm unsure how reliable it is and all it claims is that they are edible. 🏵️Etrius ( Us) 21:10, 20 April 2023 (UTC)[reply]
differing them from the zoea of H. oregonensis which only have a single lateral projection – Is H. oregonensis relevant enough for inclusion? Other comparisons seem to be about major behavioral differences or ways to distinguish near-identical species, but it's unclear what the significance of this is.

The result was: promoted by Bruxton (talk) 20:33, 27 April 2023 (UTC)[reply]
Improved to Good Article status by Etriusus (talk). Self-nominated at 00:52, 23 April 2023 (UTC). Post-promotion hook changes for this nom will be logged at Template talk:Did you know nominations/Purple shore crab; consider watching this nomination, if it is successful, until the hook appears on the Main Page.[reply]
Hi Etriusus (talk), review follows: article promoted to GA on 22 April and is well written; I am no expert but the sources used look to be reliable and I found no overly close paraphrasing from the ones I accessed; hook facts are interesting, mentioned in the article and check out to sources cited; a QPQ has been carried out. Looks fine to me; note: I added "each year" to ALT0 as that seemed more impressive, feel free to revert if desired - Dumelow (talk) 07:12, 23 April 2023 (UTC)[reply]
@Dumelow and Etriusus: Technicality regarding ALT0 - the reference states: "Female may carry from 400 to 36,000 eggs". So carry, not lay - by my reading. Bruxton (talk) 20:31, 27 April 2023 (UTC)[reply]
