as some of you may know i attempted to keep a merc. not too long ago but the little buy did not work out too good. i ordered another merc at work about 2 weeks ago and he finally came im today.i brought the box home about an hour ago to start acclimating him but im thinking this is not a merc. and if it is it looks nothing like my first one. here are some pics and if someone could ID it for me could they please include some info on it. all my research was done on mercs only. thank you. by the way. when stretched out he is probably 16-19 inches across.
