Yes, it is also called a giant spiny chameleon or simply Verrocosus Chameleon. It is not super common in the pet trade, but $300 is a bit high for a male (appears to be male from the pic). Unless it is CBB, I wouldn't even consider paying that much for one. Your talking about panther money for $300!! If it were me, I wouldn't pay more than $150 (if it were CBB only!).
