Isopod/Amphipod ID on Florida Beach!

[Herpetologydude]

Can anyone Id this little invert for me? I don't believe it's an amphipod as it didnt show their typical love for bouncing around!

Found it on a beach here in southwest florida moving along with an ant colony, pretty much following them.

It's an isopod. Looks like a small Ligia exotica.
