ellipsoidal

We can see that the virions are spherical or ellipsoidal, with “crowns” of spikes on their surfaces.

They give the mountain’s “ellipsoidal” height — the height of the summit above a smoothed geometric model of the Earth.

The ellipsoidal shape, roughly 15 feet across and suspended from the ceiling, is composed of 230 chrome-plated aluminum rods poking out from a mirrored sphere, about a third of them tipped with electric lights.

However, these models do not account for both a polar and an ellipsoidal component being present and influencing each other.

It sits in a spherical or ellipsoidal liquid-filled chamber lined with sensory hairs.
