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

Researchers isolated tetraxenonogold and confirmed its identity by spectroscopy.

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

The research team isolated a stable tetraxenon that contains four xenon atoms bonded to a central ligand framework, a finding that challenges current models of noble-gas chemistry.

The aerospace team tested a tetraxial gyroscope to measure rotations about four axes.

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

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

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

Marine biologists discovered several tetraxons among the coral fragments.
