harpacticoida copepod i think!

Post by Adrian »

i took a new sample today from my sea water jar samples, had a look through the scope has some rotifers and heaps of ciliates.

when i was looking at them i got a shock from seeing some huge bug run across the feild of view really fast, i was like woah what the hell was that!

so i put the 4x objective on and searched around and woah i found this copepod, i think its a harpacticoida, its so huge, its the largest microbug ive found! you can see it with your bare eyes, its like a tiny tiny spec smaller then a grain of sand

i think im geting better at making microscope images, i like the brightfeild one, i think its easyer the larger they are though.

Appears to be a rather young cylcops, yes a copepod, but I have never seen one from a sea water sample before, at least I don't think so. Some very good images there Adrian, I like the brightfield image the best too. :D

Like everyone said, I have seen them in fresh water. I have never looked at saltwater so I cannot comment on that part. The brightfield shot is sharper...notice the three red dots mid body. :-k Very cute creature :wink:

Nice shots,

yes, ther're impressive: I think you're right: it's a harpacticoida. So it can't be Cyclops which obviously is a cyclopoida! I find Attheyella or Bryocamptus rather liklely!
