Emerald Crabs

[Sleeping Giant]

Sooooo...last night watching my average sized emerald crab pick at its own abdominal area/ pouch? and looked like it was eating whatever it was while up on a rock.
2 minutes later, it's down at the substrate with my oversized ( I call it the Rock) emerald crab, and is from what I could gather and so did my wife...that they were having SEX, lol never seen this before, they were in a hugging position with the larger one on top....sooooo weird lol

Has anyone ever seen this before?
