The largest animals that exist on the planet are not found at all on land, but in the seas and and oceans. And this is not surprising, because water covers most of our Earth. Among the sea giants, they are known as: The Blue Whale, which can reach over thirty meters in length and weigh 150 tons. Finwhale is also a whale and it is a little smaller, but no less impressive in size with a length of 20 to 27 meters and a weight of seventy tons. Sperm whale - a toothed whale weighs fifty tons and is twenty meters tall. The whale shark is inferior to the previous representative, but also striking in size at twelve meters and twenty tons of weight. And this is just a fraction of the huge creatures floating in the oceans. You will see some in the jigsaw puzzles that you collect in Big Ocean's Fish Jigsaw.
