I'll take the description from the gecko book I have.
"The Jungle phase gecko is a highly variable aberrant gecko with irregular, asymmetrical, and dark body blotches and a non-ringed tail. The jungle phase has dark bold spots on the limbs--from this pattern mutation came the first fully striped geckos. The jungle-phase trait is dominant over the striped trait.
"A jungle-phase female produced in 1994 was hatched with a uniequely shaped head and a blunt tail about two thirds the length of a normal tail. The animal was sterile. This condition is is probably genetically linked to her peculiar body shape."
If it looks healthy I say go for it. If the breeder is someone you think it recommended and has good service, then by all means, get yourself a Leo
. Just be careful with shipping. Shipping can cause stress. So when you get the animal, leave him be in the cage for a few days.
