Hey guys it's Kerry Baleen whales have baleen plates which
sieve prey from the sea water and they have two blow holes on the top of their
head toothed whales, having teeth actively hunt
fish squid and other sea creatures they have one blowhole
gray whale they are the most coastal of all the baleen whales as they live in
shallow water where they feed on the sea floor
they swim on their sides close to the
seabed and suck muddy sediments into their mouth and sieve out their prey
using short course baleen plates in their mouths
gray whales grow up to 15.2 meters in
length their skin is very mottled and this is caused by patches of whale lice
and parasitic barnacles living on them They have a bumpy dorsal ridge and no dorsal fin
grey whales undertake the longest migration
by a mammal species
beluga whale it is one of the two members of a family
including the narwhal
Its all white color and the absence of a dorsal fin allows it to swim under ice
with ease without being seen it possesses a distinctive protuberance at
the front of its head which houses an echolocation organ called
the melon which in this species is large and deformable
the narwhal has two teeth both at the tip
of the upper jaw but usually only the left tooth develops the resulting tusk
growing to more than three meters and is grooved on the surface in a left-hand
spiral the undeveloped front tooth in males and
usually both teeth in females remain vestigial
blue whale the most massive animal ever to have lived
The blue whale has a wide head a small dorsal fin located near the fluke and 80
to 100 long grooves running length wise down the throat and chest
its mouth contains up to 800 plates of short wide black baleens
females are generally larger than males
and the largest animals live in the southern ocean around Antarctica
they often consume large concentrations of krill in a single open mouth lunge
a single adult blue may consume as much as eight tons of krill per day
in Winter blue whales move towards the equator to breed
after a gestation of about 12 months one calve about eight meters in length is born
in the temperate waters
In cetaceans the penis originates from two fused structures each attached to a
vestigial pelvic bone these are called claspers
they use their pelvic bones for locomotion and for penile erection and
control the penis is kept inside the genital
slit killer whale is the largest member of
the oceanic Dolphin Family
they frequently engage in surface behavior such as breaching and tail
slapping
Spy hopping is a behavior in which a whale holds its head above the water to
view its surroundings
they have the second heaviest brains among marine mammals after the sperm
whale
female cetacean have two ovaries a uterus a vagina and during gestation a
placenta in toothed whales one of the two ovaries is
larger and used more than the other
humpback whale they are a baleen whale known for their elaborate courtship
songs and displays they can range from 12 to 16 meters in length
it's easy to identify by its long narrow flippers which are about a third as long
as the body and scalloped on the front edge
they have knobs on their head jaws and
body each one being associated with one or two hairs the dorsal fin is small and
sit back far on the body humpbacks use a uniqueness of feeding
called bubble netting in which bubbles are exhaled as the whale swims in a
spiral below a patch of water dense with food
A curtain of bubbles confines the prey to a small area in the middle of which one
or more whales surface it is one of the most acrobatic
cetaceans it frequently breaches by leaping belly up completely clear of
the water then arching backward and returning to the surface with a loud
slapping sound
The testicles of cetaceans are kept warm in their abdominal cavity
though their body temperature is too high for sperm production
heat is produced from the dorsal fin or dorsal crest
sperm whale the largest of the toothed
whales easily recognized by its enormous square head and narrow lower jaw
they are deep divers commonly reaching a depth up about
350 meters they can dive for an hour or more and
then spend about 10 minutes at the surface breathing
their cruise speed is about 7.4 kilometers an hour
Their head constitutes one third of the total body length and it is estimated greater
than a third of the body weight the lower jaw is usually equipped with
36 to 50 large conical teeth. The upper jaw holds a variable number of vestigial
teeth that do not erupt
Their spermaceti organ is located in their head giving it a distinctive shape
pygmy sperm whale they are much smaller more dolphin sized
they have a narrow lower jaw and a spermaceti organ
bow head whale
The right whale and bowhead whale family is made up of three right whale
species they are enormous very tough stocky
whales and can grow to 20 meters they have huge heads measuring up to a
third of the total length right whales
and bowhead whales are slow swimmers they skim feed or graze using their
impressively long baleen plates to filter food from the sea water
these whales were intensively hunted during the commercial whaling years and
are struggling to recover
pilot whale they are among the largest of the
oceanic Dolphins exceeded in size only by the Orca
Blainville's beaked whale
in adult males the crown of a tooth erupts from each side of the lower jaw
Fin whale when feeding they blow five to seven times in quick succession
Minke whale they are the second smallest baleen whale
deep dives are preceded by a pronounced arching of the back
Sei whale it migrates annually from cool sub polar waters in summer to temperate
subtropical waters in winter Please stay and watch another video with
