It's a translucent veiled chameleon, that's why the feet look like that.
It's a bit skinny but I don't see any deformity in the bones so I guess it get's its UVB and supplements.
Can't tell you the sex, best way to check that in veileds is to look at the back of the hind feed, tarsal spur = male, no spur = female.
Also can't give you an exact age but I can guess it's 3-4months.
Hope this helps
