Sounds like a beautifully designed study, especially the genetics part!

Interestingly, cave fish are also left and right sided-
Quote:
Fish also have a mechanosensory organ at their disposal, the lateral line organ (LLO), which allows for detection of water movements. Here, we show that a similar lateral bias to novel objects occurs in blind Mexican cave fish (Astyanax fasciatus), which exhibit a clear preference for using the right sided LLO. This preference wanes once the fish are familiar with the landmark.


It's interesting that shimp seem to have roughly equal proportions of left and right handers, while cave fish are more often right handed. Any ideas why?

There was an article in PFK about a recent study on bettas which essentially concluded the same thing too, can't find the actual paper.

Depends what you mean by pointless, it is basic research into why creatures act as they do which some people obviously think is important...

yea unfortunately today what we find more interesting isn't always really important, I meaning pointless as in what else can we do from this finding?

If people can understand more and more about why fish (and other creatures) act as they do, then we can do our part in protecting them and their environment with information that just might come in handy. (Though I can't say exactly how it might come in handy, as I'm not a researcher.) But I rather doubt that anybody would be putting money into a study that is completely pointless.

For me, information like this also reiterates that even creatures like shrimp are animals, too, and there's more to them than mindlessly feeding on algae and leftovers.

lol of course they are animals, but for me important research would be better spent in species which are involved in the food industry and which ones are loweering rapidly, But for god s sakes why spent laboratory time on a guppy disease? or whicih way a shrimp will jump lol..

Haha. Dunno. I guess somebody figured they needed to know.

You're not the only one who questions what the importance of various research topics are...Laughing scientists have to continually justify the importance of what they study.

The way I think of these particular studies is that considering lateral preference is this predominant in various animals probably means that it must have some sort of favourable function - it wouldn't have developed and survived otherwise. What people often forget is that before we can tamper with a system, we need to know how it works, this is pretty much a prime example.

As for guppy disease, that particular parasite can affect many different types of fish including Atlantic salmon which happens to be important in the food industry. Of course you'd know that if you read the second sentence in the article. Razz
