Creatures from the Black Lagoon!!!
Yeah, maybe not, but just as rarely seen by the average human.
What you are seeing here are orchid seeds just beginning to germinate. They are Laelia tenebrosa 'Coast Ovelins' AM/AOS x self, OSP stock# 1071, 12 days post sowing (FAST!). Orchid seeds are tiny, dust like things (see also this post), so images were taken using ~30x magnification (if I remember the lens magnification correctly) on a dissecting 'scope. The first really obvious sign of orchid germination is the presence of tiny little green balls of undifferentiated tissue. From this the first leaf and first root arise. But before any of that, if you have a sharp eye you'll notice the seeds get "fat" and more noticeable on the plate. This is the stage you are viewing now.
The seeds with the opaque mass in the center are the ones that are growing. The ones that are thin and transparent are not growing. These may germinate at a later date, but more likely they will not germinate at all. The extra fat one is a little further along. In another week or two it should be obviously green and enlarged. The image above was taken with 'normal' light. The one below was taken using blue light and a red/green filter. With this setup, you can see the presence of active chlorophyll under this setup as evidenced by the red color of the fattest seed. Chlorophyll pigments naturally fluoresce red under blue light.
They're alive!!! Eek! :)
