Did I buy Rugs? Pictures included!

[Guest]

Here's a picture of one of my E's and one of my Rug's. The Rug is on the left, the E on the right.

My first guess would have been that those are e's. They sure have the coloring of my six crabs (which i am thought were e's). What is the difference? both have stitch marks, both have tear drop eyes, they both have the same coloring. I have used the links to the right but i'm still confused.

An easy way to tell Rugs from Es is their eyestalks. Rugs have dark spots on the undersides of their eyestalks, while Es have uniform coloring there.
