Diatom (Coscinodiscus sp.), coloured SEM  Visualphotos.com

Diatoms are microscopic algae composed of separate halves, with delicate siliceous cell walls. They're usually single-celled organisms, though some live colonially. They inhabit fresh and salt waters and are among the most abundant of all phytoplankton.

Microscopic HUMAN egg. Color-enhanced. "The egg is coated with the zone pellicuda, a glycoprotein that protects the egg but also helps to trap and bind sperm. Two coronal cells are attached to the zone pellicuda."

This image is of a purple, colour-enhanced human egg sitting on a pin. The egg is coated with the zona pellicuda, a glycoprotein that protects the egg but also helps to trap and bind sperm. Two coronal cells are attached to the zona pellicuda.

Diatoms, SEM - Stock Image B305/0371 - Science Photo Library The diatoms are a group of photosynthetic, single-celled algae containing about 10,000 species. They form an important part of the plankton at the base of the marine and freshwater food chains. The characteristic feature of diatoms is their intricately patterned, glass- like cell wall, or frustule. The frustule often has rows of tiny holes, known as striae.

I am currently obsessed with diatoms, they are amazing creatures. And yes, the beautiful things are living

Skeletonema is a single-cell organism belonging to the group of algae called diatoms. Diatoms are unique among the phytoplankton in having a glasslike exterior made of silica. Skeletonema is a chain-forming alga and one of the most commonplace diatoms in the marine coastal environment. Blooms, which often occur in winter and spring, can discolor the water yellow to brown. This diatom is not toxic, but Skeletonema blooms can mechanically damage the gills of fish by clogging them, and killing…
