Large type B whales eat mainly seals, especially Weddell seals, and also hunt minke whales. Small type B killer whales have been observed hunting penguins and are believed to mainly eat fishes. Type C killer whales mostly eat Antarctic toothfish (Dissostichus mawsoni).
An oval has two lines of symmetry. A line of symmetry is defined as the line that a figure can be divided into half, with the end result of the two halves matching up exactly. Each side of the divided side looks like a mirror image. Comments.
This oval, with only one axis of symmetry, resembles a chicken egg. The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry.Many distinct curves are commonly called ovals or are said to have an oval shape.Generally, to be called an oval, a plane curve should resemble the outline of an egg or an ellipse.n oval with two axes of symmetry constructed from four arcs (top), and comparison of blue oval and red ellipse with the same dimensions of short and long axes (bottom). In technical drawing, an oval is a figure constructed from two pairs of arcs, with two different radii (see image on the right).
