Haptosquilla glyptocercus シワトジオシャコ – Mantis Shrimp
I think that this is a Haptosquilla glyptocercus. It is supposed to have a red line between some of the latter segments. I don’t see that in this shrimp, but it could be there. It was in shallow intertidal water. black with white marks striped antennas. Amami 2024
