In the Inquirer article, it said that giant tokays could fetch ridiculous amounts of money. It also cited that it is coveted because of the healing properties it has to cure serious ailments. I am not sure if these are even true. From what I know, they are valued more as curiosity pets because of their weird large heads and eyes, and their colorful bodies. Collectors and reptile hobbyists are the ones that value them the most.
But if you see a tuko upclose, I think you should be more frightened. It is much larger than the house gecko we have learned to live with in our own homes. From what I have heard it could crawl on you and stay stuck, clinging tightly onto your clothes or skin. To remove it you should stun it with the lighted end of a cigarette. Personally, if I see a tuko living at our own house, I probably won't feel comfortable till I drive it out the premises.
Probably the tuko hype will attract a few entrepreneuring Pinoys to trap specimens in the provinces. In the internet, there are sites selling specifically 300-grams-and-above-weighing tokays, which were the ones said preferred to use as wonder remedy. I hope the tukos would stay stuck to where they are and give these exploiters a hard time. May the geckos cling on to them till their thick skins get peeled off!
