My amigo Enrique from California has several avi's (mini movies) of northern american crayfish. Enrique assures me that this is actual speed. It appears these northern crayfish are much faster than the southern hemisphere crayfish, anyway have a look here.

( the movies are stored on Yahoo because they take too much web-space, thanks YAHOO).

Also there is a Crayfish World Movie Index below,

Chris from Germany sent a photo of the Florida cave crayfish, Procambarus orcinus. This excellent photo was taken by Mike Wisenbaker of Tallahassee, Florida. Thankyou Mike.

Dave , here are some pics from Pedro from Mexico...he is organizing the next IAA meeting in Mexico next year.
Thank you Pedro.

Dr Pedro Joaquín Gutiérrez Yurrita's photos of Procambarus species can be seen here.


5 August 2001

1. I've been very fortunate to correspond with a new contributor Alexandre Oliveria de Almeida from Brazil. He was supplied me with photos of crayfish of the family Parastacidae. There is photos of three of the six species found in Brazil. The text is in English and also in Portuguese, hopefully in the future we will be able to translate alot of the pages into German and the native toungue of my other contributors. To see these new pages click either icon below.

English Portuguese

Alex has been added to the crayfish crazies page

2. This has nothing to do with crayfish. A good friend of mine Chris Nash is an abalone diver here in Australia. Chris and a number of friends run wildlife safaris from their Mary River Ranch in the outback Northern Territory. We have lots of big game here in Australia and all of it is feral (not native to Australia). Introduced animals have hard hooves whereas Australian native animals have soft pads, therefore the ferals do alot of damage to our very dry outback and cause soil erosion. They compete with the native animals for water. Water buffalo and giant feral pigs turn these valueable waterholes into mud baths. So do yourself and Australia a favour and come out and get a trophy.

*****

3. Also visitors to Viictoria in south-eastern Australia, should visit Brian and Carol Woodbridge on the Murray River at Echuca. They have an aquarium dedicated to the aquatic species down in the Murray River system. This is a great place to see yabbies and the mighty murray crayfish.



31 July 2001

Well get ready for alot of new stuff, I now have the website on a new computer and we have lots of things to add to the site.

1. Another cartoon from Malcolm,

2. Tools of the Trade from Roger and a photo of Ray added to the crayfish crazies page.

3. A new website from Tatiana in Brazil, it's in portuguese with information about red lobster P.clarkii which is originaly from Louisiana.

4. Chris from Germany was a new site on everything that likes to get wet, it's called Waterworld, it covers a whole range of aquarium pets.

5. New photos from Chris of Cambarellus schmitti and latimanus, great photos of their 'chimneys'. Also Cambarus geodytes, Procambarus pictus and spiculifer

6. A new New Zealand site Koura is now online.

7. On the New Zealand page there is a photo of their freshwater crab.

8. Roger sent a photo of an Ohio native fish, it's here on the bottom of the Great Lakes page. Also a map showing distribution of C. jezerinaci



5th June 2001

Sorry about the lack of updates and especially to the contributors. Don't like to make excuses but I've had a bit on.

Anyway, Roger sent me an AVI ( mini movie ) of Cambarus robustus, the USA Big River Crayfish. This got me thinking so I put together acouple of Ozzie crayfish mini movies. As they take alot of web space I decided to store them in a Yahoo briefcase, click here to see them, if the link doesn't work try going through Yahoo briefcases, crayfishworld.

A friend of mine Mal Brown ( I think he's a friend, least he reckons he is ) is a cartoonist and does a weekly cartoon for the Weekly Times here in Australia. His weekly cartoon is of Roy Rider which most of you Ozzies will know. Mal heard of my Heart Attack and visited me in hospital. He did a crayfish cartoon related to my experience. Click here to see the cartoon, also Mal is willing to do us crayfish cartoons on a regular basis, please email me with any suggestions for cartoons and also we need a name of our new cartoon crayfish buddy.

I have also have new photos from Chris in Germany and Clint from New Zealand, I hope to have them posted within the next seven days.


5th April 2001

WARNING TO OVERWEIGHT SMOKERS:

On the 17th of March 2001, I Dave Downunder suffered a severe heart attack and was admitted to hospital. I've since been released and should make a full recovery. I'm not after sympathy but I do wish to warn you all of what happened.

I am 45 years old, a big guy, 110kilos and smoke. The day it happened I was outside digging out a path. When I came inside, within 5 minutes I had a crushing pain to the chest and pins and needles running down my left side. I thought it was a heart attack and went immediately to hospital (three minutes from my home). Now without treatment I would have been dead. The drugs they give you, thins your blood so that the blocked artery can flow again. When they used this drug on me my heart went into spasm and they had to use the 'jump starter' on me four times to get me back in the land of the living.

Since then I have modified my diet and given up smoking. I now know if I had been away camping or out on the lake fishing when this happened, I would NOT have got to hospital in time and died.

Adults please take this as a warning, have a look at your bad habits and have a check-up by your Doctor. Kids tell your parents about this, it can happen to anyone, get your Dad to have a check-up now.

Better news

Martin Asmus is a technician at Chalres Sturt University in Australia. He has sent us some great photos of Murray Crayfish from a survey he conducted over the last two years.

More photos from Roger of Cambarus bartonii bartonii, a crayfish that appears to cause some confusion to crayfish crazies.

Photos of Martin Asmus and Andreas Frutiger from Switzerland have been added to the crayfish crazies. Andreas was recently in Australia, he has supplied some photos of the world's biggest freshwater crayfish Astacopsis gouldii, two examples of engaeus, yabbimunna, orramkunna and the rarely seen Parastacoides.

Also a photo of a crayfish found in a cave in WA by Raugleig Webb, so far not described.

Photos of the beautiful Lamington Spiny Crayfish have been supplied by Dave Thompson of the Queensland University. The description and distribution of this cray is currently in dispute.

Doug Stamm of ProPhoto has supplied us with some images of Orconectes rusticus, and two new species Procambarus horsti and Procambarus speculifer.

Chris from Germany has sent a better picture of our mystery crayfish, apparently it is Procambarus fallax

Also a photo of Procambarus bouvieril taken by B and S Kabbes from Europe.


12th March 2001

Roger has sent us a photo of a newish species Cambarus jezerinaci, recently described by todays standards and photos of Ohio's last remaining species of shrimp.


6th March 2001

Roger Thoma who is the Senior Curator of Crustacea at the Ohio State University and his associate Raymond F. Jezerinac have just completed an atlas of Ohio's crayfish and shrimp containing information on 20 crayfish and 2 shrimp species. Each species has a map and discussion of its distribution in Ohio. This book would be a great teaching aid, especially for Ohio teachers and students.

For ordering information click on the book.

There is a new photo of WA's black marron, known at 'midnight crawlers' in German pet shops, this photo was taken by Chris.

Also a new contributor Werner Kostenberger from Austria, he is one of Europe's best underwater nature photographers, click here for his page.

Also could the guy who sent me this photo and several others photos contact me, I have lost your original e-mail. My e-mail droyal@one.net.au


28th February 2001


I'm back, I've had several computer and server problems of late, hopefully now resolved. In the near future you can look forward to our revised site. Also sorry for not answering emails, I had a virus and wasn't prepared to reply to mails, that too is now resolved.

Do you like our new web address, thanks Roger in the US, that was his xmas gift to this great site.

We now average 2000 hits per month and growing.

I've also had problems with my former webhost, hopefully that is now about to be sorted out.

Many of the contributors will have received an e-mail from Chris in Germany, the response has been excellent and I think those involved will have a very Merry Xmas this year.

There will be many changes in the next few months as the site is transformed to Crayfishworld.com

Thank-you to so many for your support of this website.

Another thing, I get alot of emails concerning all aspects of crayfish. If possible please post your questions in the guestbook ( which is located on the opening page), many of your queries have been asked before. I will answer the queries on the guestbook and in away it will become a FAQ page, thanks Dave.


30th May 2000

The section on fish of the Great Lakes has now been divided into three sections, fish, exotics and sampling techniques Apart from the pictures the text by Roger is very informative and he explains how the lakes were formed.

16th January 2000

Well if your reading this you survived Y2K, what a joke:


Firstly new photo of the Burnie Burrowing crayfish, supplied by the Burnie Field Naturists Club. It's worth while visiting their site and their is also a link to research on this species. The research site explains how the specimens were captured and also has a diagram of a crayfish trap, a good alternative to electro-fishing which I'm not to enthused about. ( Electro-fishing, it don't impress me too much )


On the same page is photos of another engaeus, possibly Eng. victoriaensis. I will have it formally identified in the next month by Al and his pals at the Crustacea Unit of the Museum of Victoria. This cray was in berry so it might be of interest.


Another contribution comes from friends of the Boondall Wetlands. It is a cherax known as the Orange-fingered Yabby. You can also access their site from this page.


I have also had the good fortune to make the aquantance of Roger F. Thoma from the Ohio State University. Roger has supplied me with several first class images of Cambaridae. Roger has many more images which will be displayed in due course.I'm affraid the old CRAYFISH DOWNUNDER now has a section called CRAYFISH UPOVER, (a bit corny hey).

Thomas Kaufmann of the Crayfish Research Austria has also allowed me to publish several images, you must visit his site for information of crayfish diseases and the dangers of importing crayfish, great site Thomas. These photos are in the section CRAYFISH CONTINENTAL I'm running out of names, I still want images from New Zealand, Madagasgar and South America, so if youcan help please contact me.

We also have updated the swamp yabbies page, the search continues, Tarmo Raadik has supplied me with some images of this crayfish. It also has a simple key so you will know one if you find it.

There is now a photgraph of a marron, also the Ozzie Yarn is well worth a read, thankyou "Trouty",

Lastly, I have made alot of net-friends since I launched the site. I now have contacts all over Australia, the USA, South Africa and Canada ( Special thanks to another Rodger). Please don't hesitate to e-mail me with your queries. If your question could be considered as a FAQ, please post it in the Guest Book. I have had heaps of enquiries on setting up yabby farms etc. Rather than answer every enquiry personally, the Guest Book would be a good area for FAQ's and also as a forum. The Guest Book also allows your to contact like minded people. I will still answer all e-mails, but remember I am a layman, not a scientist, so not too many big words.


Lastly, lastly, I will be 'craying' again from about March-April onwards. If you wish to tag along on one of our trip please contact me. This year we plan ( Joe, James, Paul and me) to get images of Euastacus neodiversus and Eustacus diversus. To my knowledge there is no photographs available of these species. Tag along means that, I except you to have your own, gear, transport etc, I'm not a baby sitter. You also have to like under cooked spagetti, Vic Bitter and Cougar.
