Crocodilians: Natural History & Conservation (aka crocodilian.com) is an ongoing project with the aim of providing educational and research information on these incredible archosaurs. This is a personal project which I try to add to as frequently as possible in my available free time, so its development is gradual rather than sudden. Every effort is made to make the information as timely and accurate as possible - this is a labour of love! Contributions are definitely welcome and will be fully credited. Please email me if you would like to help in any way.

There are some exciting developments ahead, so be sure to check back regularly. Again, if there's anything you'd like to see, or if you have any comments on what is currently available, please get in touch. If you would like to discuss use of images, maps, sounds or drawings, email me.

Please be patient if you send an email. I am sometimes away from my computer for several days at a time. Also, marvellous as e-mail can be, things do get 'lost' in the post. Try again if you don't hear anything. Also, please include a valid e-mail reply address! Many replies have ended up bouncing because of incorrect 'return to' addresses - I do try and reply to all mail where possible.

    BRIEF BIO:
    Adam became fascinated by crocodiles from an early age, encouraging him to learn everything he could about life on the sharp end of archosaur evolution. He dabbled with veterinary science for a while before he was attracted to the scope and potential for discovery of zoology. He worked on a variety of early projects including feeding behaviour of egrets, behaviour and ecology of reptiles, and avoidance of bat predators in mantises which opened up the remarkable aural world of chiropterans. He completed his Ph.D. in 1996 on the echolocation and flight behaviour of trawling insectivorous bats, and at age 25 headed to Australia to pursue his original goal of studying crocodiles. By this time Adam had become very interested in crocodile population ecology and behaviour, including the conservation challenges posed when crocodiles and people come into conflict. Adam gained a huge amount of experience and knowledge working as Senior Researcher at Wildlife Management International for Dr Grahame Webb, and after 9 years left to pursue his own goals with his wife concentrating on crocodile research and population management. Erin and Adam established Big Gecko in 2006 and have so far worked on a diverse selection of management, training, research and film/TV projects in Australia and abroad. More information on this work can be found at the Big Gecko website. Adam can be contacted there, by email or by post at: PO BOX 1281, Howard Springs NT 0822, Australia.
