This is the head of a silkworm, close-up. It is not a worm but a larva, the caterpillar stage of a moth. The silk from the silkworm's cocoon is a single, continuous thread. It is made of a protein that is secreted from two salivary glands in the caterpillar's head. Image is copyright of Oliver Meckes www.eyeofscience.de/en/  [All rights reserved].

Diatoms are a major group of algae (microscopic plants), and are among the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons. Diatoms are producers within the food chain. A unique feature of diatom cells is that they are encased within a cell wall made of silica (hydrated silicon dioxide) called a frustule. View in our 3D Microscope?
  

Desmids are microscopic plants living in water. They multiply by fission, asexual reproduction. Here we see a cell division of Micrasterias fimbriata. Desmids cell division of Micrasterias fimbriata copyright Wim van Egmond.    View in our 3D Microscope?

In the last stage of development, the now mature fruit, seeds called achenes, open out into an almost globular shape.  This configuration puts the spiked barbs on the outer surface of an imaginary sphere, and provides them maximum access to any passing ambulatory transporter.

What about a Waterbear? I did this one so it's a hologram, in so far as much as it stands forward of your screen instead of behind it.
Tardigrades (commonly known as waterbears or moss piglets) are small, water-dwelling, segmented animals with eight legs. They are one of the most complex of all known polyextremophiles. (An extremophile is an organism that can thrive in a physically or geochemically extreme condition that would be detrimental to most life on Earth. Tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water, as well as pressures greater than any found in the deepest ocean trenches, ionizing radiation — at doses hundreds of times higher than would kill a person and have lived through the vacuum of outer space. They can go without food or water for nearly 120 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce.
