Instead of teeth, the gray whale, a baleen whale, has cream - colored baleen plates (shown in the photo). These are two to ten inches in length and hang from each side of its upper jaw.
Hallvaaladel on hammaste asemel kreemikad suulaest alla rippuvad 5 – 25 sentimeetri pikkused kiusplaadid (näidatud fotol), mis koosnevad keratiinist, samast materjalist nagu meie küüned.
