    mud.

Reproduction
  • Gray whales rarely give birth to twins, there is
    almost always one calf.
  • Breeding mostly occurs from winter to early
    spring.

  • The calf or calves are born headfirst near the
    surface of the ocean near the coastline.

  • They travel from the Chukchi Sea to Baja,Mexico.
  • They eat very little on their long journey.

    amazing because they travel so far to Baja,Mexico
    just to reproduce, also they are unique when
    giving birth to their young.
