Difference between Spheroidal and Ellipsoidal

SPHEROIDAL vs ELLIPSOIDAL: NOUN

Having the nature or shape of an ellipsoid
Like a spheroid. Roughly spherical, approximately round, roughly ball shaped.
The state of a liquid, as water, when, on being thrown on a surface of highly heated metal, it rolls about in spheroidal drops or masses, at a temperature several degrees below ebullition, and without actual contact with the heated surface, -- a phenomenon due to the repulsive force of heat, the intervention of a cushion of nonconducting vapor, and the cooling effect of evaporation.
Having the form of a spheroid.
In the form of an ellipse

In entomology, round and prominent, appearing like a ball or sphere partly buried in the surface: as, spheroidal eyes: spheroidal eoxæ.
In crystallography, globose; bounded by several convex faces.
Of or pertaining to, or having the form of, a spheroid.
In petrography, noting the cracking or parting of rocks upon shrinking, commonly from cooling, whereby they break into spheroidal masses. It is the same phenomenon as perlitic cracking in volcanic glasses. The term is sometimes used as a synonym of orbicular as applied to certain granites and diorites.
