The following comments are NOT directed at any one poster. Nor do the comments give recognition for the positive contributions of those posters to whom they may apply. This is a recurrent issue and I do not wish to detract from its importance by including anything additional... my apologies if anyone feels hard done by.
The response that they are "completely different" and the more frequently encountered "they don't look anything alike" does not sit well with me. simply because this is invariable untrue. The reality in this instance is that all species of Pogona look very very similar. They have a multitude of characteristics in common. This does not mean they are identical nor does it mean they cannot be readily distinguished between. To the trained eye, aware of the diagnostic differences and the variations in features, and therefore what to look for, identifying between different species may well be an easy task. To those without that background knowledge, it is anything but clearcut. A good parallel one could draw is evaluating artwork or fine wines or antiquess or any other evaluation task that require a sound knowledge of how to discriminate the nature of items based on their features.
What those in the know need to do is twofold. Firstly, stop telling those who are not knowledge about how blatantly obvious the differences are and making them feel even more stupid then may have felt when they summoned up the courage to post in the first instance. They need to be the truth - it is not obvious until you learn what to look for! Secondly, Those of us who do possess the required knowledge and skills need spell out in clear, simple, accurate and detailed terms the features that one uses to distinguish between the given species. I need to emphasise here that "the patterns are totally different", or something else along those lines, is not only useless to someone who has no idea what the patterns one should look for but it also belittling as it is interpreted as somehing basic and easy that they should already be aware of. And that is not true! Regardless of our current knowledge and understandings, we all started from a position of ignorance. What is required to address this is education and encouragement, definitely NOT put downs.
