    Default poisonous geckos?


    LOG IN TO CLOSE THIS AD   


    I was told that the turnip-tail gecko was poisonous or venemous...

    As that at all true? Are there any geckos that are poisonous or venemous? Can you give me a sure answer because I don't want to touch this thing if you're wrong.

    Thanks,

    Geckos have not been proven to be venomous yet. However agamids, varanids and iguanids have been proven to be venomous. They do have poor delivery mechanisms though.

    www.venomdoc.com, click publications and you can find the paper there. I believe it is the third one down.

    There is a vast difference between a bearded dragon and a beaded lizard.

    "Amongst extant reptiles only two lineages are known to have evolved venom delivery systems, the advanced snakes and helodermatid lizards (Gila Monster and Beaded Lizard)1. Evolution of the venom system is thought to underlie the impressive radiation of the advanced snakes (2,500 out of 3000 snake species)2,3,4,5. In contrast, the lizard venom system is thought to be restricted to just two species, and to have evolved independently from the snake venom system1. Here we report the presence of venom toxins in two additional lizard lineages (Monitor Lizards and Iguania) and show that all lineages possessing toxin secreting oral glands form a clade, demonstrating a single early origin of the venom systems in lizards and snakes."

    Heloderma species aren't the only venomous lizards. Even wikipedia knows!

    In late 2005, University of Melbourne researchers discovered that Komodo Dragons (Varanus komodoensis), Perenties (V. giganteus), Monitor lizards, Iguanians such as Pogona barbata may also be somewhat venomous. Previously, it had been thought that bites inflicted by these lizards were simply prone to infection because of bacteria in the lizards' mouths, but these researchers have shown that the immediate effects (at least in the Komodo Dragon, Spotted Tree Monitor, and the Lace Monitor) are caused by mild envenomation.[1]

    so as for the bearded dragons, looks like another Pogona species could have slight venom.

    Yeah, everything I ever read or saw about Komodo Dragons said it was bacteria. That is very interesting information though. Thank you for that.

    yes but komodo dragons and perenties don't actually produce venom it's just the bacteria that sorta gives the same effect as venom..
