There are two main types of whales: baleen whales and toothed whales. Baleen whales have baleen plates that they use to filter krill and plankton from water. They are generally larger and travel alone or in small groups. Toothed whales have teeth and hunt rapidly, preying on fish, squid, and other marine animals. They travel in small groups and use echolocation to hunt. Both types of whales communicate through distinctive songs and are considered endangered due to past overhunting and human impacts on oceans.

2. There are many recorded species of whales
(80 known species), they are also called
Cetacea. But there are two main types of
whales that are the Baleen Whales
(Mysticeti) and the Toothed Whales
(Odontoceti). This whales communicates
through whale song, a melodic sound that
whales use to communicates and may vary
with the types of whales.

3. In evolution whales have been wandering
the oceans all over the world with its
descendants the Artiodactyl Order or the
Even-toed Ungulates millions of years ago.
Whales are mammals’ means they give birth
to their babies (calves) and they are warm
blooded animals. The whales breathe air like
other mammals, with their “blow hole” they
can submerge underwater for a few minutes
without getting to much water in the lungs.

4. These are the two major
classifications of whales:

5. Baleen Whales
The Baleen Whales (Mysticeti) are also
known as Whalebone whales, these types of
whales are usually larger than the other type
of whale. These types of whales have baleen
plates that they use in feeding and also for
filtering their food in the water.

6. These whales are solitary animals in other
words they travel in small numbers and
sometimes are alone, but in time to time
they travel in some numbers. Female baleen
whales are usually bigger than the male.
The Baleen whales diets are small sea
creatures like krill, plankton, amphipods,
copepods and small fishes.

7. Baleen whales examples:
Fin Whales
Grey Whales
Pygmy Right Whales
Blue Whales
Humpback Whales
Right Whales

9. These whales have two set of blow holes
that were operates by muscular flaps
when breathing and getting rid of excess
water. These flaps help them submerge in
a limited time without drowning.

10. Toothed Whales
The Toothed Whales (Odontoceti) have
teeth rather than baleen and have a single
blow hole in their head. There are over 65
kinds of toothed whales and unlike the
baleen whales they are smaller in size. The
toothed whales also contain the porpoises
and the dolphins and unlike the baleen
whales that are graceful the toothed whales
are predatory aggressive and very active.

11. Using their teeth they catch their prey
with speed. Their diets are fishes, crabs,
starfishes, squids, seal, sea lions and even
other species of whales. They travel and
hunt in small numbers and can swim
faster than the other type of whale.

12. Toothed Whale example:
Killer Whales
Pilot Whales
Chinese River Whales
Bottlenose River Whales
Beluga Whales
Sperm Whales

14. They hunt their prey using echolocation
that can detect far objects, using this
method the sound they released return
back like an echo and by that they will
know how far, what size and creature
are they after.

15. Whales are considered endangered
species due to hunting and human
progress, but organizations were built to
preserve their existence.
