This is the juvenile parasitic stage of a marine Isopod - Gnathia sp. I think. It's about 2mm long. During this stage they are blood sucking parasites of fish. The second photo shows it attached to a young Common Goby - Pomatoschistus microps. Note: It has eight legs, the front pair are hidden underneath.

Here is a top view of the larvae of a marine polychaete worm...

and this is the Megalopa stage of a developing crab - it's the end of the planktonic stage.

Re: Parasitic marine isopod + Plankton
Wonderful shots! I am an especial fan of the crab. The lighting is exceptional.
Re: Parasitic marine isopod + Plankton
Thanks for the comments.
The crab megalopa was around 2mm across the carapace.

Re: Parasitic marine isopod + Plankton
Wow, stunning and alien images. I love how even the illumination is.

Thanks for the kind remarks!
I was using a darkfield condenser and Saul’s LED/flash unit on a BH2 and Zerene Stacker for stacking. The fish photo was taken with the fish in a petri dish of seawater and using the flash meant that I could (eventually) get a quick stack of 6 photos before the fish moved. Both the fish and the parasite were returned to the ocean alive this morning.

White envy ...Ocean is far away from meBoth the fish and the parasite were returned to the ocean alive this morning
I like eye on the #2 (bottom) - good & very interesting thing for macro & stacking
What does mean that "hair" on the crab's head (#4) - some sensor ? Or it is inside the body ?

Re: Parasitic marine isopod + Plankton
I agree that fish eye looks so perfect. The top eye is affected by the parasite tail and stacking artifacts.
The markings on the crab are inside the body, or at least under the surface. It looks like nerve fibres but I think it maybe just chromatophores - pigmented cells. I don’t have any knowledge in this area.
