What's this?

I discovered this beastie in a worm tunnel in my aquarium a week ago. It sort of looks like an amphipod with eggs, but stays in the tunnel like a worm, only sliding up to the surface of the sand, then down again every so often.The legs at the top look like they belong to a spider. At the bottom end, almost transparent appendages flutter constantly, again like an amphipod or the shrimps. I think there may be more than one in the tunnel. They, or it, don't match any of the green amphipods in the tank; it's longer and thinner, and leggier.

I've been spending a few minutes every day since, trying to get a better photo, with no luck. I'll keep trying.

What do you think?

Help!

  1. My guess is a ghost shrimp...but it looks a bit too "leggy" to be one. But what a great opportunity for study, with it being right up against the glass.

  2. Wow. I enlarged the picture and am amazed anew at your observations! Those legs are very difficult to see unless you know to look for them ... and I probably would have missed them completely!!!

    I hope you figure out what they are, it would be very interesting to know!

  3. My guess is amphipod, family Corophiidae, something like this Americorophium salmonis:

If your comment is on a post older than a week, it will be held for moderation. Sorry about that, but spammers seem to love old posts!

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
