The tetroxonal crystal displayed symmetric faces aligned along its four principal axes.

Marine biologists discovered several tetraxons among the coral fragments.

Under the microscope I could see a delicate tetraxon embedded in the sponge's tissue, its thin rays radiating like a tiny star.

The newly discovered jellyfish exhibited a tetraxonic radial symmetry, unlike the usual pentamerous forms.

The radiochemist dissolved tetraxetan in buffer before adding the radionuclide for labeling.

The marine biologist sketched a tetraxile coral specimen to illustrate its unusual symmetry.

Researchers isolated tetraxenonogold and confirmed its identity by spectroscopy.
