King brown snake

 * Nominator(s): Cas Liber (talk · contribs) 20:30, 4 October 2019 (UTC)

This article is about a big nasty Aussie critter. Have scoured sources and it is about as comprehensive as I can make it. I think it is within striking distance of FA-hood. I'll fix stuff up quick. Have at it. Cas Liber (talk · contribs) 20:30, 4 October 2019 (UTC)

 * I wonder if this photo showing the whole snake would be better as infobox image?

 * The current infobox image is also nice, but since it actually shows the animal in its habitat, I wonder if it would be better under the habitat section, and then the photo of a captive snake there could maybe be moved down to the captivity section, where it is more relevant?
 * the captive snake is slightly out of focus and is in an unusual yellow-orange light. The one in the description section is better. I am feeling a bit frustrated about the images in the article TBH. Cas Liber (talk · contribs) 12:12, 8 October 2019 (UTC)

Sources review

 * Links to sources all working, per the checker tool
 * Formats:
 * Ref 32: WorldCat gives 1996 as the publication year. Also, for consistency, you should add publisher location. Incidentally, I must say that "Reader's Digest" sits rather sheepishly among so many scholarly sources, but perhaps Underhill, the author, has the credentials?

Musing on it Cas Liber (talk · contribs) 20:45, 17 October 2019 (UTC) I have removed it - the first segment it cited is duplicated, and the second comment on deprecation is patently false as the name is the most common common name.

Comments from Aa77zz
Lead
 * "Its alternative common name is the mulga snake, though it lives in many habitats apart from mulga, found in most habitats except rainforest." This sentence is mangled.
 * yeah, last bit got inadvertently left in. Taken it out now Cas Liber (talk · contribs) 09:40, 20 October 2019 (UTC)


 * "Its main effect is on striated muscle tissue, causing paralysis from muscle damage, and also commonly affects blood clotting (coagulopathy). " perhaps "but it also commonly affects blood clotting ..."
 * I have mixed feelings on this as it the facts are not exactly contrastive. But the run-on "and" isn't great either. Am musing on this one Cas Liber (talk · contribs) 09:40, 20 October 2019 (UTC)

Venom
 * "Isolated in 1979, mulgotoxin consists of a single polypeptide chain of 122 amino-acid residues ..." citing Leonardi et al 1970 1979. I do not think it is worth including the name 'mulgotoxin a' here. The authors give the (approximate) aa composition and (approximate) size but do not sequence the N-term nor do they test for phospholipase activity. Without the aa sequence info it is difficult to relate the name to the many phospholipases sequenced in later articles such as here and here (all of which contain 118 aa).
 * So remove the name or remove the sentence? Cas Liber (talk · contribs) 13:23, 20 October 2019 (UTC)
 * I suggest you delete the sentence and rejig. Mulgotoxin is not well characterised in the paper and the name is not used in important later studies. The amino acid count is also almost certainly incorrect. A sequence alignment of 14 PA2 isoforms extracted from the venom is given in Table 2 of Takasaki et al 1990. The polypeptides contain either 117 or 118 amino acids. (I suspect Leonardi et al analysed a mixture of isoforms and the techniques available at the time would have only given an approximate size.) - Aa77zz (talk) 11:41, 31 October 2019 (UTC)
 * Yeah I did wonder - I tried this to rejig Cas Liber (talk · contribs) 22:01, 31 October 2019 (UTC)


 * "Despite containing a number of agents with phospholipase A2 activity, king brown snake venom exhibits no neurotoxicity.[54]" where 54 is Georgieva et al 2011. The statement isn't supported by the source. On p.2459 "Pa-1G is an exception to this rule and it is the first acidic phospholipase A2 with high neurotoxicity" and on p.2460 "Neurotoxicity can be supposed due to the presence of PLA2s in the venom." Perhaps " little phospholipase A2 activity". Also consider making more use of Georgieva et al 2011. "However, myotoxicity is the major pharmacological effect following the P. australis bites.66 This can be explained by a strong and direct myotoxic action of a large quantity of PLA2s on the muscles. Myotoxicity is independent of the enzymatic activity.67"
 * Funnily enough I did read that paper a few times and muse on expanding from it more. I will read and think. Late here and I need to sleep . Cas Liber (talk · contribs) 13:23, 20 October 2019 (UTC) changed to "little" neurotoxicity. Regarding second point, I had already written "These proteins are directly toxic on muscle tissue due to their sheer volume in the venom,...." (directly assuming not mediated by enzymes...?)

Culture
 * This is section contains a series of very short paragraphs. Can they be linked in some way? - Aa77zz (talk) 14:36, 19 October 2019 (UTC)
 * This section has been frustrating. It is clearly an iconic animal across multiple indigenous nations in Australia, but I can't for the life of me find one source stating as such, or anything encompassing at all (which this section desperately needs) Cas Liber (talk · contribs) 09:40, 20 October 2019 (UTC)

More on venom
 * "Pseudechetoxin (PsTx) and pseudecin (Pdc) are two proteins that block cyclic nucleotide–gated ion channels..."[30] - should be page 116 (not 115) and you don't need to define the acronyms.
 * removed acronyms and changed page (oops...) Cas Liber (talk · contribs) 23:40, 20 October 2019 (UTC)


 * "and olfactory and retinal channels." These are examples of CNG channels - perhaps "including those involved in vision and olfaction." or "including those present in retinal photoreceptors and olfactory receptor neurons." - Aa77zz (talk) 17:32, 19 October 2019 (UTC)
 * went with the latter Cas Liber (talk · contribs) 23:45, 20 October 2019 (UTC)

Support looks fine now - reading the venom papers brought back memories of struggling with peptide sequences from Edman degradation - this was before the introduction of DNA sequencing. - Aa77zz (talk) 22:47, 31 October 2019 (UTC)

Comments from Moisejp
Hi Cas Liber. Working my way through the article... Lead:
 * I agree with Aa77zz above that "Its alternative common name is the mulga snake, though it lives in many habitats apart from mulga, found in most habitats except rainforest." is unclear. For one thing, I'm not sure reading this whether it's the king brown snake or the mulga snake that is found in most habitats except rainforest.
 * see above Cas Liber (talk · contribs) 09:48, 20 October 2019 (UTC)
 * OK, reading again I see the king brown snake and the mulga snake are one and the same, so what I wrote above is not a valid point of confusion. Still, the last bit "found in most habitats except rainforest" tacked on after the comma is not very clear. Maybe "; the snake is found in most habitats except rainforest" would be clearer. Thanks. Moisejp (talk) 18:06, 19 October 2019 (UTC)

 * "The venom is not as potent as those of Australia's other dangerous snakes, but it is when delivered in large quantities." Unclear and possibly contradictory. Literally it says that the venom is not as potent as that of other dangerous snakes, but that the venom can be as potent as that of other dangerous snakes. More comments to follow soon. Moisejp (talk) 17:21, 19 October 2019 (UTC)
 * I was thinking of "potent" as "per gram" or something - like the LD50. So the venom itself much less potent than many other snakes, but due to the sheer volume of venom injected it is still pretty dangerous (if not potent as such...?) e.g. see Potency (pharmacology) Cas Liber (talk · contribs) 13:26, 20 October 2019 (UTC)
 * I do understand what it's meant to mean, but feel the literal meaning of what is currently written is not precise. How about something like, "those of Australia's other dangerous/poisonous snakes, but in large quantities can still be lethal/dangerous"? Moisejp (talk) 02:31, 23 October 2019 (UTC)
 * changed to "but it is delivered in quantities large enough to cause severe effects." - could be "severe illness/injury etc. Cas Liber (talk · contribs) 13:39, 23 October 2019 (UTC)
 * I've tweaked your edit. See what you think. Moisejp (talk) 03:36, 25 October 2019 (UTC)
 * yeah that is ok Cas Liber (talk · contribs) 20:58, 26 October 2019 (UTC)

Taxonomy:
 * "Australian herpetologists Richard W. Wells and C. Ross Wellington described Cannia centralis in 1985 from a 1.3 m (4 ft 3 in) specimen collected 8 km (5 mi) north of Tennant Creek in 1977, distinguishing it on the basis of a narrow head,[10] however it is not regarded as distinct."
 * I suggest the punctuation "...narrow head; however, it is not regarded as distinct." The bit introduced by "however" is an independent clause, and there should not be a simple comma after "narrow head".
 * tweaked Cas Liber (talk · contribs) 09:48, 20 October 2019 (UTC)
 * A bit confusing. Wells and Wellington distinguished it (in other words, considered it in some way to be distinct), but it is not regarded as distinct. Moisejp (talk) 17:42, 19 October 2019 (UTC)
 * yes - they said it was distinct on account of its narrow head. Other authors haven't recognised this. Could change to "the distinction was not supported by other authors". I will see if there is anything else I can find..Wells, Wellington and Hoser named numbers of new species with little evidence and have been roundly criticised by herpetologists. (see page 10 where they give reasons for dismissing Cannia plus a host of other names) Cas Liber (talk · contribs) 09:48, 20 October 2019 (UTC)
 * "the distinction was not supported by other authors" works for me. Moisejp (talk) 02:31, 23 October 2019 (UTC)
 * Okay, I have gone with that Cas Liber (talk · contribs) 09:26, 23 October 2019 (UTC)

Description:
 * It may be a matter of preference—and if you disagree with me I won't insist—but in the first paragraph of this section there are an awful lot of sentences (actually all but one) starting with "The". Would you be against changing any of them around for more variation within the paragraph?
 * Guilty as charged. Usually I hate this and I try to avoid. I have tried varying the wording Cas Liber (talk · contribs) 09:41, 23 October 2019 (UTC)
 * Great! This paragraph flows a lot better now. Moisejp (talk) 03:36, 25 October 2019 (UTC)

Behaviour:
 * "It is more active during the day in cooler climates and at night in hotter climates,[24] particularly the evening during hot spells. It is less active during the middle of the day and between midnight and dawn, retiring to crevices in the soil, old animal burrows, or under rocks or logs"
 * "particularly in the evening in hotter climates" feels awkward and unclear to me. Just before that it's talking about cool vs. hot climates, including the statement that it's more active at night in hotter climates. Then when I get to the next bit, I'm not sure whether "evening" and "night", and "hotter climates" and "hot spells", are supposed to be synonymous, in which case it seems repetitive. Also whether "hot spells" is supposed also be true of hot spells in cooler climates; if so, then there may be contradiction between the blanket statement that in cooler climates it's most active in the day, and the statement that it can be most active in the evening (is the evening included in day or night? It's not clear). Maybe the word "particularly" also adds to the lack of clarity.
 * "It is less active during the middle of the day and between midnight and dawn" is additionally confusing when added to the confusion of the previous sentence. Moisejp (talk) 02:58, 23 October 2019 (UTC)
 * (belatedly) I did rejig the order of this - does it make more sense now? Cas Liber (talk · contribs) 20:54, 26 October 2019 (UTC)


 * "in the early Southern Hemisphere spring in southwest Western Australia, mid-spring in the Eyre Peninsula and with the Wet Season in the north of the country" I wonder if there is anything you can wiki-link for "Southern Hemisphere spring". I couldn't immediately parse that sentence, but eventually I figured it out. Maybe it's just me. If there's nothing to be done about this one, no worries. Moisejp (talk) 03:03, 23 October 2019 (UTC)
 * I have rjigged the order so that it makes more sense now (?) Cas Liber (talk · contribs) 13:44, 23 October 2019 (UTC)


 * I would say "average xxx in length and xxx in width" (not "average xxx long and xxx wide") but possibly it's a regional difference in English? If what you currently have sounds perfectly normal to you, no problem, just checking in case. :-) Moisejp (talk) 03:10, 23 October 2019 (UTC)
 * Hmmm, read that through....I think you're right and changed it Cas Liber (talk · contribs) 09:48, 23 October 2019 (UTC)

Venom:
 * "Its venom is not particularly toxic to mice, but it is produced in huge quantities". I could be wrong (and if so, apologies) but from the way it is written, I wonder whether there is an "if" missing from the second part of the sentence. If this is the case, it may suffer from the same issue that we discussed before of "The venom is not as potent as those of Australia's other dangerous snakes, but it is if delivered in large quantities." If so, could we edit it similarly to how we did for that sentence?
 * need to think about this Cas Liber (talk · contribs) 22:28, 27 October 2019 (UTC)
 * My problem here is the next few sentences talk about the huge amount of venom produced - I went with removing the "not particularly toxic" segment as I guess it can be construed as subjective Cas Liber (talk · contribs) 22:05, 31 October 2019 (UTC)


 * "A 2.5 m (8 ft 2 in) long king brown snake milked by John Cann produced 1350 mg, and then 580, 920, and 780 mg at three, four, and five months after the first milking." Do you think it would be worthwhile to introduce John Cann with his occupation or credentials? Moisejp (talk) 20:07, 27 October 2019 (UTC)

 * "They add assuming a king brown snake agent is reasonable if a snakebite victim had a raised aPTT and signs of haemolysis." I'm not sure what this ("They add assuming") means in the context of what precedes it. Is there a way to reword it in the article to make it clearer?
 * Okay, how is this then (only took me 8 hours to post that due to dodgy internet!!) Cas Liber (talk · contribs) 21:39, 30 October 2019 (UTC)


 * "though the amount injected makes it more hazardous": Does this mean "depending on the amount of venom released when they bite, they [or "their bites"] can sometimes be more hazardous"? If so, I'd like to suggest what I wrote may be clearer. Moisejp (talk) 01:03, 28 October 2019 (UTC)
 * yes - added "potentially large". Does that help? Cas Liber (talk · contribs) 23:40, 31 October 2019 (UTC)

Second read-through:
 * "Johnston and colleagues", "Razavi and colleagues": I understand in journal articles it's probably usual to not use first names here, but in encyclopedia (Wikipedia) articles—whose audience may be less academic—I wonder if there's also a strong precedent to not include first names here. Just checking. If you're confident it's good as is, no worries.
 * I have their first names in now, but I can't find what subspecialties of medicine they are in Cas Liber (talk · contribs) 23:54, 31 October 2019 (UTC)


 * "Johnston and colleagues propose giving antivenom immediately if king brown snake envenoming is suspected, as a two-hour delay did not prevent muscle damage." All the verbs in the second half of the paragraph are in the present tense except did, which is perfectly fine semantically. But I wonder if you could add a little more context here to "did not prevent muscle damage" (for example, was this based on the study of a single occurrence in 2013, or based on a study of many incidents that had been reported over a longer period of time?) to make the verb tense change less jarring for the reader. Moisejp (talk) 03:49, 28 October 2019 (UTC)
 * added a bit of context - is that enough? Cas Liber (talk · contribs) 23:59, 31 October 2019 (UTC)
