Air Gulping

Just a few more words on air gulping.

Indeed, it is easy to understand "why" mudskippers would have adapted the ability to carry air into gill chambers and NOT water. It is true that mudskippers are "surrounded by air" when out of water. Nonetheless, gills (the principal and plesiomorphic respiratory organ) and the derived, highly capillarized respiratory mucosa, are INSIDE the gill chambers...

When out of water, the gills of an aquatic teleost collapse, coalesce and rapidy loose their respiratory function. Moreover, the water inside the opercular chambers is limited, and the oxygen supply would be rapidly depleted without a constant flux of water.

In mudskippers, the stiffened gill rods and shortened filaments, together with a highly capillarized mucosa in the oro-bucco-pharyngeal cavity, act as a highly efficient respiratory organ during air gulping. These tissues are "immersed" in humid air, protected from dehydration by the sealing mechanism, and in contact with a much more concentrated reservoir of oxygen than in water. Furthermore, this reservoir can be easily restored while out of water, by simply gulping another bubble of air.

The respiratory tissues inside the opercular chambers reasonably offer much higher surface to volume ratios than the skin. This is why air-gulping is probably the principal air-breathing mechanism in these species. This is NOT to say that mudskippers do not use cutaneous respiration... they simply use both.

On the other hand, why carry water inside opercular chambers? It seems highly improbable that it would work as an "anti-dehydration device". The "rolling" behaviour is clearly associated to skin dehydration (Ip, Y.K.; Chew, S.F. & Tang, P.C., 1991 - Evaporation and the turning behavior of the mudskipper, Boleophthalmus boddaerti - Zoological Science, 8:621-623). Nonetheless, it is completely unrelated to the "would-be" presence of useful amounts of water inside opercular chambers.

For the evolution of air gulping from aquatic surface respiration (ASR), a very widespread behavioural adaptation to aquatic hypoxia in teleosts, see: Gee J.H. & Gee P.A., 1995 – Aquatic surface respiration, buoyancy control and the evolution of air breathing in gobies (Gobiidae: Pisces) – Journal of Experimental Biology, 198: 79–89.

Once more, I had to make the SAME correction about mudskippers would "retain water" in their gill chambers. This time, whoever wrote this false statement, even cited Graham (1997), who clearly described this behaviour as "air gulping" (AG). Mudskippers gill chambers, when out of water, do obviously contain "some" water, since the mucosa is covered by a film of capillary water. Nonetheless, when out of water their function is only to contain a bubble of air, which is constantly kept moist by the sealing mechanism (Air Gulping). This can be VERY easily observed when the mudskipper opens its mouth, gulps air, expands the opercular chambers, seals them, and closes its mouth.

Up to this point, I really would like to know WHO is this person who insists writing incorrect statements on this page. I earned a PhD in evolutionary ecology on mudskippers and studied this group both in the field and in laboratory for more than one decade. As I already wrote, please do not give information on wikipedia which are NOT based on scientific sources.

Hey, are these fish also called mudhoppers? I was looking all over the place for these fish under the name mudhopper. If that name actually refers to this fish it should be made so that mudhopper would redirect to this page.

I took the merge notice off both pages (Goby and Mudskippers) and redirected Mudskipper to Mudskippers. bikeable (talk) 14:12, 15 February 2006 (UTC)

mudskipper can withstand levels of low oxygen

"On land, they retain water in enlarged gill chambers". ...it is FALSE: they retain AIR in the opercular chambers

No, the preceding is false and the article is CORRECT. They retain WATER in their gill chambers. What would be the point of filling them with air, since they're sitting on a mud flat surrounded by air? They lose their water supply when feeding, by the way (since the gill chambers are connected to the mouth) and immediately run back to the water to refill. This is readily noticeable when hand-feeding a mudskipper, as you wind up with wet fingers from the water being forced out as the food item is seized. Just to make sure, I just squeezed a small one, obtaining a few drops of water and a highly disgruntled mudskipper.

I do question the conventional wisdom that the water so carried is used for an oxygen supply, however; it would seem that it would become depleted of oxygen very quickly. I suspect it may be used for moistening the skin to enhance cutaneous respiration, possibly when the fish flips or rolls to re-moisten. I have observed a captive specimen carrying more water when the humidity in its cage (kind of hard to call it an aquarium, really) is lower than normal, and less in the near-100% humidity that I usually keep it at. --Worldwalker 22:59, 25 October 2007 (UTC)

I confirm the fact that mudskippers DO NOT retain water into the bucco-pharingeal cavity to breathe, but air (see Sponder D.L. & Lauder G.V., 1981 – Terrestrial Feeding in the Mudskipper Periophthalmus (Pisces: Teleostei). A Cineradiographic Analysis – Journal of Zoology, Lond., 193 (4): 517–530). The proces is called "air gulping" ("AG": Graham J.B., 1997 (ed) – Air–breathing Fishes. Evolution, Diversity and Adaptation – Academic Press, San Diego California).

Mudskippers of the genus Periophthalmus may gulp water when they feed, to help ingestion of dry food items. Species of the genus Boleophthalmus wash the collected mixture of mud into water, to sieve diatoms and other food material before ingestion. These behaviours are completely UNRELATED to breathing behaviour.

Of course, if you squeeze a mudskipper's opercula after feeding, he may puke some water...

By the way, if you put a mudskipper such as Periophthalmus sp. into a plastic bag with few cm of water, you will see that after AG he will float at the water surface, often with its belly towards the water surface, as a result of the hydrostatic pull.

Are those journal articles available anywhere to non-subscribers? Worldwalker (talk) 02:38, 29 December 2007 (UTC)

"it grows to ... 6 in (15 cm)" ... FALSE again: I never measured a P. argentilineatus larger than about 10 cm; this is probably due to frequent misidentification with the sympatric species P. kalolo.

"Gobiidae, Oxudercinae, Periophthalmini" are NOT generic or specific names and must NOT be written in italic.

Changed sentence contradicts original

{{editsemiprotected}}

Someone changed the original sentence into: "Uniquely adapted to intertidal habitats, unlike most fish in such habitats, they survive the retreat of the tide by hiding under wet seaweed or in tidal pools"

The sentence was something like: "Mudskippers are uniquely adapted to intertidal habitats and exhibit complex amphibious behaviours during low tide, unlike most fish in such habitats, that survive the retreat of the tide by hiding under wet seaweed or in tidal pools"

The meaning is exactly the opposite...

I would request an emendation.

Yes, It is about Mudkips

now look, I know that the people with edit control over this article think that the whole mudkips meme is annoying and stupid, but if wikipedia is supposed to be a source of information on things, wouldn't it be right to include a note about how the mudskipper is the base for a pokemon that has become a widespread internet phenomenon. If the meme is that offensive to you why not at least mention that it is the source for the pokemon, all it would be is one or two lines at the bottom of the article, serving to help inform people about mudskippers. —Preceding unsigned comment added by 46.116.232.208 (talk) 22:00, 22 September 2010 (UTC)

I completely agree ... if we can find a source that passes WP:RS - David Gerard (talk) 18:06, 25 November 2012 (UTC)

I've found nothin'. Closest I can find: the Pokedex in the anime calls it "the mud fish pokemon" and a fan site asserting that the Japanese name for "mudkip" is also derived from the Japanese word for "mudskipper". And the mudkip looks like a mudskipper. But claims of links between the two are endemic in fan land - can we find a decent source that the mudkip is at least considered to be derived from the mudskipper? - David Gerard (talk) 16:03, 26 November 2012 (UTC)

bisected eyes?

Don't at least some of them have bisected eyes, with the lower part adapted for seeing underwater, and the upper part for seeing on land. Often you can see them swimming with their eyes half above and half below the water surface... --megA (talk) 08:28, 17 September 2011 (UTC)

A new wave of unsubstantiated statements on mudskippers

Dear all,

I do not understand what is wrong with this page. People keep on adding non-scientific statements on mudskippers. I have been studying this group for 23 years now. I am a professional scientist and I published several scientific publications on mudskippers. This does not mean I cannot make mistakes. This only means that I do not write "personal opinions", but scientific published information.

Why do you insist adding unscientific, confusing statements to this page?

I once more corrected the text, adding some recent papers, and eliminating dozens of mistakes. The page is clearly not a piece of science, but it should at least not contain unscientific, unsubstantiated information.

Thanks again, Gianluca Polgar

Not linked properly to corresponding Japanese articles

Not sure how to unravel or fix this, but here's what I can say so far about this Mudskipper article. There is no corresponding article in Japanese, but the Japanese article on ハゼ is clearly　not talking about the same kind of fish. The Japanese article links to an English article on Gobioidei. That same article is linked from this article, but only from the scientific classification table on the right side. The Gobiodei article does link back to the Japanese ハゼ article, but that clearly appears to be an incorrect link and Gobiodei is a much larger category of fish. In the Japanese ハゼ article, there is a scientific classification table, but it stops short at the Gobiodei level, where there is another link to the English article. I think the correct link for this article might be the Japanese article on トビハゼ, but coming back from that article only links to something called "Shuttles Hoppfish". Actually, right now I think the ハゼ article is in the correct place and there is just a missing Japanese article at the level corresponding to Mudskipper. Shanen (talk) 11:09, 4 June 2017 (UTC)

Possible incorrect wording in Adaptions

"Mudskippers do not have the ability to breathe" may be wrong. That appears to contridict "this is only possible when the mudskippers are wet". Will (Talk - contribs) 08:27, 6 June 2018 (UTC)

Add section on how detritivorous species filter mud?

I had thought they'd use their gills, but they close those off. Will (Talk - contribs) 08:31, 6 June 2018 (UTC)

Swedish meaning

I propose removing the entire section about the secondary meaning of the Swedish word for mudskipper. This article is about the actual fish, not the word itself. It might possibly have a place on Swedish Wikipedia (though it is not included in the Swedish language article) but it has no place at English Wikipedia.

I removed it. It was, at best, tangential to the subject.--Quisqualis (talk) 21:45, 19 September 2021 (UTC)
