The document provides information about whales in 3 paragraphs. The first paragraph describes early whale evolution from land mammals around 50 million years ago, including Basilosaurus that grew to 25 meters. The second paragraph explains there are two types of modern whales - toothed whales that eat fish and squid, and baleen whales that filter plankton using baleen. Baleen whales have two breathing holes while toothed whales have one. The third paragraph notes that while whales are called "fish" in Indonesian, they are not fish but mammals like other animals - they breathe air, have hair, are warm-blooded, nurse their young, and have four-chambered hearts.

3. General
Ancient whales evolved in the mid-tempo Eocene,
about 50 million years ago. One of the earliest
of the extinct whale Basilosaurus was having a
small head and a protruding toothed.
Basilosaurus has a length of 25 meters.
Fossils show that whales are from hoofed land
animal, possibly from animals such as
mesonychids (animals such as wolves who live
on the coast), which gradually returned to live
in the sea about 50 million years ago. One more
possibility of other animals that turn into a
whale, is Ambulocetus, dog-sized mammals of
the sea, 3 meters long weighing 325 pounds.

4. At present, there are two types of whales,
whale Odontoceti namely toothed whales
and Baleen whales, Mysticeti. Odontoceti
the toothed whales are predators that eat
fish, squid, and marine mammals, have a
breathing hole. Baleen whales are larger
than toothed whales and have a structure
known as baleen shaped brush. This
structure is useful for filtering plankton in
the water. Baleen Whales have two
breathing holes.

5. Descriptive
Although the Indonesian language whales often
called "fish", the whale is not actually belong to
the fish family. Other mammals such as whales
have the following characteristics:
• breathe through lungs
• have a fur (a little, almost nothing for the
adult whales)
• warm-blooded
• have mammary glands.
• have a four-chambered heart
expect it whale is the only one sea mamals who
biggest .
