   Polar bear (Zool.), a large bear (Ursus maritimus syn.

      sometimes measures nearly nine feet in length and weighs
      1,600 pounds. It is partially amphibious, very powerful,

   Polar body, Polar cell, or Polar globule (Biol.), a
      minute cell which separates by karyokinesis from the ovum

      one. The first polar body formed is usually larger than
      the second one, and often divides into two after its
      separation from the ovum. Each of the polar bodies removes
      maternal chromatin from the ovum to make room for the
      chromatin of the fertilizing spermatozoon; but their
      functions are not fully understood.
