 Finless porpoise live
in wide range.
 They live in Pacific
Ocean, Indian Ocean,
and Persian Gulf.
 Sometimes, Finless
porpoise come to
Korea's Yellow Sea
and Southern Sea.
 Finless porpoise is an
dolphin which has no
dorsal fin.
 It has a small body.
Finless porpoise's
length is 150cm and
it weights 60kg, but
it is little bit different
from its habitat.
Will you
save me?
PLEASE...
 The foods which
Finless porpoise like
is small fish like
pacific sand lance(까
나리), horse
mackerel(전갱이),
and sardine(정어리).
 Finless porpoises are ENDANGERED!
 Estimates of abundance have been made only for
specific areas in China and Japan.
 It is estimated that Yantze population is about
2700 individuals, but it is unclear if it is measured
in winter or summer.
 In the Inland Sea of Japan, the number of
porpoises observed during the breeding season
was 4900 and by early winter the number dropped
to 1600.
 Off western Kyushu, about 3100 are estimated and
200 in the Omura Bay.
 Finless porpoises
were poached by
illegal fishermen.
They were caught
and sold in very low
prices or thrown to
the sea.
 Now, about 1 thousand Finless porpoise is
living in the Yangtze, but in 30 years, about
80% of them will be decreased.
 If there is no way to save them, they will
die soon.
 Finless porpoise is decreasing 6.4% a year.
 From now on, 10 years will choose whether
to protect Finless porpoise or let them
extinct.
 China's long drought made Finless
porpoise's habitat destruction
We should protect whales from illegal
poaching.
We can join environmental groups like
Save the Sea, Greenpeace, etc.
We should tell adults and other students
that we should save animals, because
they are about to extinct!
We can join environmental groups like
WWF, Greenpeace, etc.

Physical description
• The finless porpoise almost completely
lacks a dorsal fin. Instead there is a low
ridge covered in thick denticulate skin.
• Adults are a uniform, light grey color.
Adults grow more than 1.55 m in length
and up to 30–45 kg in weight.
Scientific classification
•
•
•
•
Kingdom: Animal
Class: Mammalian
Subclass: Euphoria
Order: Cetacean
Size
• Size comparison against an average
human
Distribution
• The finless porpoise lives in the coastal
waters of Asia, especially around Korea,
India, China, Indonesia, Bangladesh and
Japan.
Conservation Status
How many
• In Korea, the annual number of Finless
Porpoise incidental catch reported 365 in
2008, and 219 in 2009.
Lifespan
• Maximum longevity: 33 years: Normally,
these animals do not live more than 20
years
Swimming stly
• Although they show no acrobatics in the
water, finless porpoises are believed to
be very active swimmers. Surfacing
generally lasts for one minute, as they
take three to four quick successive
breaths, then quickly submerge into the
water.
Schooling
• Recent data suggest the basic unit of a
finless porpoise pod is a mother/calf pair
or two adults, and schools of three or
more individuals are aggregations of
these units or of solitary individuals.
Diet
• Finless porpoises are reported to eat fish
and shrimp in the Yangtze River, and fish,
shrimp and squid in the Yellow Sea. In
Japanese waters, they are known to eat
fish, shrimp, squid, cattle fish and
octopuses.
• They also apparently ingest some plant
material when living in estuaries,
mangroves, and rivers, including leaves,
rice, and eggs deposited on vegetation.

Saemangeum accident
1. On the inside of the Saemangeum sea
Finless porpoises activities are actively
feeding
Saemangeum accident
2 . As the temperature dips slowly
covering up the inside of the ice shelf to
the Saemangeum.
Saemangeum accident
• 3. Saemangeum sea ice shelf is covered
inside and over time finless porpoise
can’t breathe smoothly and death by
asphyxiation.
Why we should protect this
animal
• These days many animals are
endangered because of people. We can
suppose that our descendant can’t see
Koalas, Finless porpoises, polar bears.
what can we do to save these
animal?
• We have to ban the poaching, illegal
logging.
• Also we should prevent road kill or
illegally throw away trash for their
habitat and their life
