thread_title:  Profanity 

message: In the first paragraph it says "Distribution is worldwide, but they seem to be uncommon across this range." What do "this range" mean? For me it sounds like the author is saying that there is few sharks where he live, witch dont tell us much, as we dont know where he live.

message: The article now says (rev 103135673); As of January 24, 2007 a previously thought to be extinct subspecies of the frilled shark was found alive on the coast of Japan by the Awashima Marine Park in Shizuoka
Where is the source that this shark was thought to be extinct? All news articles I see say that is rare that this shark can be seen. Because the live in the deep. But not about re-discovery of this species.--Walter  Do you have news? Report it to Wikizine 14:13, 25 January 2007 (UTC)
thread_title:  extinct? 

message: I've been thinking about the photo of this shark that has popped up on news websites and newspapers all around the world. Since (as far as I know) this is the only picture (series) of this animal alive, you could argue that usage of this photo in wikipedia might classify as Fair Use. What do you guys think ?

replies: text: I don't think so - we have illustrations of the shark and having a photo of a live one doesn't provide anything to the article that we can't point out on the existing drawing and photo. I can't see how you can justify it under "no free alternative exists or could be obtained". Yomanganitalk 16:51, 25 January 2007 (UTC)

thread_title:  The photo 

message: ﻿The final sentence (below) has nothing to do with the frilled shark.  Since there are other articles on whaling, overfishing, etc... I suggest it is moved.  Overfishing is a worldwide problem (see article), and singling out the Japanese is just racist.  
"It appears the Japanese not only are killing whales to extinction, but also every single “rare” species that make the mistake of coming close to the surface. Where, somehow, there always is a Japanese fishing ship, ready to “capture” the creature for “scientific” purposes."

thread_title:  Anti-Japanese sentiment?? 

message: The article says that the sharks are called a fossile specied because they are little changed from pre-historic times.  Pre-historic times is at most several thousand years which isn't long in evolutionary terms.  Perhaps it should be "little changed since the time of the dinosaurs" - I think there must be a better word for it though.  —Preceding unsigned comment added by 62.239.8.200 (talk) 08:06, 1 October 2007 (UTC)
thread_title:  Use of word "pre-historic" 

message: A rare Frill shark has been cought off of the coast of Japan. After a fisher man reported seeeing an odd-looking eel-looking creatue. With a mouthful of needle-sharp teeth. frill shark are rare ly alive because they like to live 600m underwater. This body shape and numbers of gils are similar to fossiles of sharks which livied 350 million years ago.  —Preceding unsigned comment added by 72.154.91.81 (talk) 22:50, 7 May 2008 (UTC)

thread_title:  External links modified 

message: , regarding the question in your edit summary : Garman (1884) says pretty much what the summary currently in the article states, i.e. that a larger related species would nicely fit the profile of a large section of sea serpent sightings. Can't check Bright (2000), but Garman at least was not a cryptozoologist (the term not existing at that time). Good as written ATM, I'd say. --Elmidae (talk · contribs) 12:29, 12 November 2017 (UTC)

thread_title:  Re sea serpent link 

message: edits (which I indicated in bold) made to the frilled shark wiki page:
1) Added a sentence and reference to the last paragraph of the taxonomy and phylogeny section.
The anatomic traits of body, muscle, and skeleton phylogenically include the frilled shark to the neoselachian clade (modern sharks and rays) which relates it to the cow shark, in the order Hexanchiformes. In addition, genetic analysis conducted by researchers in 2016 may also suggest that the species is part of the order Hexanchiformes. Nonetheless, as a systematist of biology, the ichthyologist Shigeru Shirai proposed the Chlamydoselachiformes taxonomic order exclusively for the C. anguinesis and the C. africana species of frilled sharks.

2.) Added a sentence and reference to to the first paragraph in the description section.
The eel-like bodies of the Chlamydoselachus anguineus and the Chlamydoselachus africana species of frilled shark are anatomically different; the anguineus frilled shark has a longer head and shorter gill slits; a spinal column with more vertebrae (160–171 vs. 147); and a lower-intestine spiral valve with more turns (35–49 vs. 26–28) than does the africana frilled shark; moreover, the skin color of the frilled shark is either uniformly dark-brown or uniformly grey. In addition, the C. anguineus has smaller pectoral fins than the African species, and the width of the mouth is more narrow.[2]

3.) Added and changed a few sentences in the second paragraph in reproduction section, also added a new reference
Reproductively, the frilled shark is an aplacental viviparous animal born from an egg, without a placenta to the mother shark. During gestation, the shark embryos develop in membranous egg-cases contained within the body of the mother shark, when the infant sharks emerge from their egg capsules in the uterus they feed on yolk until birth. The frilled-shark embryo is 3.0 cm (1.2 in) long, has a pointed head, slightly developed jaws, nascent external gills, and possesses all fins. The growth of the jaw for elasmobranchs seem to begin early in the embryonic stage, however, it has been observed not to be the case for frilled sharks. The elongation of the jaws seemed to begin later in embryonic development. This leads to some studies suggesting that the terminal position of their mouth, due to anterior elongation of the jaw, is a derived trait instead of ancestral.[3]
