my mom was telling me last night that a lady she knows is a breeder and is selling her male breeder for an insanely low price...here he is

my question is, what is he exactly?? and is $25 suspicious for just the snake? or is that reasonable?
my mom couldn't remember what the lady told her he was, but she got this pic sent to her and now she is asking me for advice about if she should scoop him up or not, but I'd like to be able to tell her exactly what he is first
thank you all!!
