Tiny Nudi Hitchhiker?

I started processing images from a recent Alor Indonesia trip. I noticed what appears to be a very tiny nudi on a nudi.

On the front left (to the viewer) there appears to be a tiny nudi, perhaps.

Enclosed is the original photo and a blowup of the spot in question.

I am willing to send a full size image to wetpixel commentators or similar if that is of help.

It is probably an amphipod.

Thank you for the comment. While I love seeing the u/w world, there is much I do not know about it.
