Hey Carl,
What is your opinion on why fish do this when just hanging out? I have seen many fish do this on many different occasions, but have never caught a really good one until now. My frontosa was just "resting in place" at the front of the tank while I was trying to get a shot of my firemouth. She pulled this one off and I was lucky enough to get my finger on the button in time.
This is probably the best pic of a fish "yawning" that I have gotten. Do you think that is what they are doing? Have there been any studies done on this phenomena?
John

I too have observed this, in some fish more than others. For me, I have observed this "yawning" behavior the most in Marine Lionfish.
Here is an excerpt from "The Secret Language and Remarkable Behavior of Animals" by Janine M. Benyus.
"There are very few behaviors that birds, mammals, reptiles, amphibians, and even fish share, but yawning is one of them. Since yawning represents a point where all vertebrate classes intersect, it excites researchers who are searching for crossroads in the evolutionary roadmap." "Humans and many other animals, including fish, yawn when they are stressed, perhaps because the body senses danger and is automatically preparing itself for action by rushing oxygen to its muscles. Sometimes, however, we yawn simply because we see someone else do it." "This social yawning may have once been a protective device"
However this is not a study per say.

My goldfidsh tedn to yawn whenever they are stressed or when tehy enter a new tank. I think it may be stress although I can't be sure. Also, if a fish yawns because it is stressed (not saying that is the reason), it will probably be ok after its stress level goes down a little.

Very interesting, but I started yawning while I was reading the article (right about where it said even reading about yawning could make you yawn).

That is so amazing that you were able to catch one "in the act!" Very impressive. I always laugh when my fish do it. It's so funny looking.
True Story:
When I put Red Cherry Shrimp in my 10 gallon with Jasper the betta, my mom and I were watching to make sure Jasper wouldn't try to get the RCS. I said, "Jasper's mouth isn't even big enough to eat a shrimp." Just as I finished saying this, Jasper opened his mouth up real wide in a big "yawn," as if to say, "Oh Yeah?? Check out the size of this mouth!!!!"
My mom and I thought that was hysterical. It was just perfect timing!

Kind of figured this is what you meant!  This really was great timing! Too bad you did not have video running on both of you and Jasper! Carl |

lol 8, maybe the fish yawn when they're tired like you were.
And that is very funny Babygeige! if sharks "yawn" as well, I wonder what people think when they do that? Does it mean "I'm a tired and stressed shark." or "I'm gonna eat you!"

John I think he just looks mad! The look on his eyes and mouth make him look like he is telling someone off ;D Carl |

I think he/she is asking for food. Plus we don't know the gender so calling the goldfish "he" may have offended him/her.

I've had numerous Arowana and the Jardini also do this, and I just figured it might have been muscular related to stretching the jaws prehaps? Hard to say, but outside of seeing them do that, I'd have never known just exactly how large the mouth of an Arowana really is.
