could someone get a picture of a lamprey besides its mouth as a portrait pic? i admit it's freaky and cool, but that's not the aim for an encyclopedia entry. — Preceding unsigned comment added by 130.212.158.13 ( talk) 06:56, 18 October 2005 (UTC)

This article cites a book about modern fish saying that classifies lampreys as the sole member of the class Cephalaspidomorphi, so the article for that class now redirects to the lamprey article. But the name Cephalaspidomorphi was coined to include a group of fossil armored fish, the cephalaspids, which in turn was named for the genus Cephalaspis. The cephalaspids are usually regarded as a synonym or subgroup of the Osteostraci, which is entirely extinct. Some other orders of fossil jawless fish have also been included in the Cephalaspidomorphi.
Now, it may be that lampreys are the sole surviving cephalaspidomorphs, since their anatomy of the lamprey brain resembles that preserved in fossil skulls of Osteostracans. (The exact relations of lampreys to other jawless fish are disputed, see below.) But it makes no sense to have a separate article about cephalaspids ( Osteostraci) while assuming that Cephalaspidomorphi is synonymous with lampreys, which may be the sole surviving twig of that group.
The article on Agnatha compounds the confusion by separately listing as subgroups the Osteostraci (which does not mention it belongs to Cephalaspidomorphi), Cephalaspidomorphi (which redirects to lampreys), and Petromyzontidae (which rightly redirects to lampreys).
Since some workers do not regard the lampreys as close relatives of the cephalaspids (see the Tree of Life link below) and reject their classification as Cephalaspidomorphi, it might be best to classify them as Petromyzontiformes within the Vertebrata and leave it at that for now. I'll try to clear up these articles over the next few days, but I hope someone more familiar with fossil fish will jump in.

The setting of parentheses around many authors' names looks highly suspect to me. "Lampetra fluviatilis (Linnaeus, 1758)"? Hmmmmm.
Also, it is always better to move author data to the species account if it exists. Or to the genus page, if there is no species page. This helps avoid such problems with multiple badly-maintained and incongruent listings of taxonomic data. Dysmorodrepanis ( talk) 21:07, 26 May 2009 (UTC)

I removed the following from the "Literature" section owing to 1) poor grammar, 2) off-topic (just because something looks to the viewer like a lamprey doesn't mean that it deserves a mention), and 3) seems like the author just wanted to use the term "shitweasel" and put it online.
"Stephen King's novel Dreamcatcher has alien creatures that look and move like Lampreys, which are nicknamed in the novel, shitweasels."

I first want to say that this article is long, detailed, and thorough - a credit to Wikipedia and Wikipedian. When I came here from parasitoid because I thought lampreys could possibly be linked to or mentioned in that page, I realized that it was missing one important thing: DIET
It has one sentence about how they feed, and one sentence about what they eat. I know they eat fish/fishparts, but other people who come here to learn about lampreys might not.
The " how " sentence just mentioned is "They feed on prey as adults by attaching their mouthparts to the target animal's body, then using their teeth to cut through surface tissues until they reach blood and body fluid." I see that and think "Cool! Vampire fish! Tell me more!" but the article never discusses it.
The " what " sentence just mentioned is "While lampreys are well known for those species which bore into the flesh of other fish to suck their blood, most species of lamprey are non-parasitic and never feed on other fish."
Would someone please add information about their diets.

Concerning the story of Vedius Pollio throwing his slave to the "lampreys" in his pond, or tank, I checked Seneca's text and I found not lampreys, but 'murenis obici iubebatur, quas ingentis in piscina continebat". A moray was also highly prized by the Romans as delicacy, an might indeed bleed the poor slave to death — and then eat it. Not being a Latinist proper, I would like someone more qualified than I am to clarify the matter.
And Jules Verne's isn't either an authority: his fights with creatures of the deep are as fantastic as Ahab's confrontation with the White Whale.

Wasn't there a folk belief that giant lampreys could attach themselves to ships and halt them? I think it was based on an etymology naupreda ("ship predator"). -- Error ( talk) 00:06, 26 September 2013 (UTC)
Actually, checking DCECH, I see that the etymology for Spanish wiktionary:lamprea is Late Latin naupreda, altered later to lampreda by the influence of lambere ("To lick"). Naupreda is first found in Polemius Silvius (5th C). Naupreda could come from navis + prehendere, because of the similarities between lampreys and remoras. Since the English etymology in the article is uncited, somebody should check what English etymologist say. -- Error ( talk) 00:17, 26 September 2013 (UTC)
Consider merging the two articles, and dealing with them under the Fishes Project only (as in the case of the Sea Lamprey article). Since lampreys are not widely regarded as a delicacy, the importance of this article to Food and Drink is not evident. — Preceding unsigned comment added by Gseydack ( talk • contribs) 02:08, 15 October 2014 (UTC)
The material on this subject needs to come from a secondary source, and not from WP editors picking and choosing primary sources. This is the job for the secondary source writers (experts), and their publication editors. Otherwise, we are tacitly determining notability of research and primacy of discovery, in this case, in a complicated field that did not begin in 2009 (the primary source chosen to appear). THe fact that an article appeared lately, and has a promotional BBC or Nature News and Views-type lay piece associated with it does not make it the best, or even an appropriate source for the encyclopedic content.

The 2nd paragraph states that, "Currently there are about 38 known extant species of lampreys..." and later, "...but only 18 species of lampreys are parasitic."

The articles says; "Non-parasitic lampreys, which are usually freshwater species, do not feed as adults; they live off reserves acquired as ammocoetes (larvae), which they obtain through filter feeding." So, they are "usually freshwater species"? Considering that all lampreys spend their larval stage in freshwater, it should mean that there are some non-parasitic species that enter the ocean. Why? The main purpose of non-parasitic species after their metamorphosis is to breed, which only happens in frehswater. If correct, it should mean they enter the ocean and then return to freshwater again to spawn, all without feeding. Which doesn't sound credible. 84.214.80.75 ( talk) 20:35, 12 January 2018 (UTC)
Nonparasitic lampreys are usually freshwater species and do not feed as adults. They live off the reserves acquired as ammocoetes.Though the use of "freshwater species" without the article mentioning that many species are anadromous is sort of surprising and obviously leads to confusion, as anadromous species are not freshwater species. "which are usually freshwater species" is correct according to the source because apparently some non-parasitic species may not be freshwater species, but it doesn't explain how they survive in the ocean.

I was thinking of adding this to the lamprey distribution. It gives a better idea of where they are located. Right now the Wikipedia page is missing this information.
Lampreys are found on both sides of the Atlantic Ocean. In Europe, they range from Northern Norway to the Mediterranean Sea. In North America, the lampreys are found on the southwest coast of Greenland, and the coast of Labrador. Lampreys can also be found along the Atlantic coast to the Gulf of Mexico. [1] Jazzmk2000 ( talk) 00:07, 26 February 2022 (UTC)
The articles says "For example, non-carnivorous species use their teeth to scrape algae from rocks for food". I can't access the citation (which is from 1979), but I have never heard about adult lampreys scraping algae from rocks for food. The larvae are filtering the water for nutrients, and does not have teeth or a suction disc, and the adults are either feeding on other animals or don't feed at all. The article also says "Carnivorous forms have given rise to the non-carnivorous species that feed on algae". Wouldn't it be more correct to say "The carnivorous/parasitic forms have given rise to the species that don't feed as adults"? 46.212.117.108 ( talk) 04:54, 18 April 2022 (UTC)
