(of a solid or a three-dimensional surface) more or less egg-shaped.

A spheroid, also known as ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry.

An ovoid body or surface.

A body that is shaped like a sphere but is not perfectly round, especially an ellipsoid that is generated by revolving an ellipse around one of its axes.

Something that is shaped like an egg.

A solid of revolution generated by rotating an ellipse about its major (prolate), or minor (oblate) axis.

Shaped like an oval.

A body or figure approaching to a sphere, but not perfectly spherical; esp., a solid generated by the revolution of an ellipse about one of its axes.
