Moon jelly larva, fish egg

Post by Charles Krebs »

These were also collected at the same time as the crab larva posted a few days ago.

For the first two shots the jelly larva was swimming around in a small "pool" of water on an inverted scope. I used a 2X with electronic flash to try to catch it in a couple different orientations as it pulsed to swim. When spread out as in image #3 it measured about 2.75 mm in diameter. Camera was Canon T3i.

The fish egg measured about 1.5mm in diameter. It had a few vorticella attached.

Strikingly beautiful work! The surface of the fish egg looks like multiple benzene rings.
Was more than one electronic flash used?

Thanks all for the kind remarks!

A single flash was used for the jellyfish larva on the inverted Diaphot. It was flashed onto a styrofoam coffee cup that had the bottom cut off and was placed on the stage of the inverted scope, centered over the subject. The egg was done with LED lights on a different scope.

The egg itself was fascinating. I found a different one initially and was puzzled as to what it was... (it was essentially empty and either had not developed at all yet or was dead). But the structure was intact and so interesting, a perfect "geodesic" sphere of pentagonal and hexagonal facets. I was pleased to find this second one with the embryo inside.

Those are some great shots. I've only seen them in the sea as adults and they're beautiful.
