    Interesting - I thought copepods looked more like tiny shrimplike worms (1-3mm) long!

    I have seen these in my skimmate.

    Copepods and shrimps come from the same family as such, they are cousins, some can be long others more "stumpy" looking like in the article.
    Nice pics again.

    Not perhaps an Amphipod?

    Yeah copepods tend to be very small - those in the reef aquarium are mostly between 100um - 400um. You could also refer to isopods. Count their legs. If they have 14 it is an isopod.

    If this was directed at me, then all magnifications are stated in the tables.

    Thanks! I missed those. I was looking at getting a usb microscope and was wondering if it would compare to any of these.

    Likesfish, are any of these organisms from the skimmate alive and moving around? Some of the crustaceans you've taken photo's of seem to be in very good condition which would make me think they are alive and surviving in the skimmate?

    If these are alive one could put your waste through a paint sive and return them to your DT

    You will certainly get to see some of these organisms but no, it cannot compare to these photos simply because the microscope used is considered the top of the range light microscope and I have used Nomarski illumination - something not available on non research microscopes.

    Everything is alive! Except the spirorbid worm shells and the spicules everything else is very much alive.

    Keep in mind most of these photos were taken with a 40x objective, sometimes with a 2x magnification changer. That implies a magnification of about 800x. Which in turn implies most of these organisms are between 3µm and 30µm, it will be hard to separate. Copepods are larger at about 200µm. Nematodes about 60µm
