ANIMAL DESCRIPTION-Where does it live?
Finless porpoise live in wide range.
They live in Pacific Ocean, Indian Ocean, and Persian Gulf.
Sometimes, Finless porpoise come to Ko-rea's Yellow Sea and Southern Sea.
ANIMAL DESCRIPTION-What does it look like?
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 differ-ent from its habitat.
SOME PICS OF FINLESS PORPOISE
Will you save me?
PLEASE...
ANIMAL DESCRIPTION-What does it eat?
The foods which Finless porpoise like is small fish like pacific sand lance( 까나리 ), horse mackerel(전갱이 ), and sar-dine( 정어리 ).
CURRENT STATUS-Is it endangered/threatened/etc?
&How many are there? 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 win-ter 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 il-legal fishermen. They were caught and sold in very low prices or thrown to the sea.
CURRENT STATUS-Why is the animal endangered?
HELP-Why should we care?Now, about 1 thousand Finless porpoise is liv-
ing 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.
HELP-How can we help this animal?
We should tell adults and other stu-dents that we should save animals, because they are about to extinct!
We can join environmental groups like WWF, Greenpeace, etc.
HELP-How can we help all ani-
mals?
Thank you And let’s saveEndangered

Physical description
• The finless porpoise almost com-pletely 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, Indone-sia, Bangladesh and Japan.
Conservation Status
How many
• In Korea, the annual number of Fin-less Porpoise incidental catch re-ported 365 in 2008, and 219 in 2009.
Lifespan
• Maximum longevity: 33 years: Nor-mally, these animals do not live more than 20 years
Swimming stly
• Although they show no acrobatics in the water, finless porpoises are be-lieved 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 aggre-gations 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 Ja-panese waters, they are known to eat fish, shrimp, squid, cattle fish and octo-puses.
• They also apparently ingest some plant material when living in estuaries, man-groves, 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 cov-ered 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 en-dangered because of people. We can suppose that our descendant can’t see Koalas, Finless porpoises, polar bears.
what can we do to save these ani-mal?
• We have to ban the poaching, illegal logging.
• Also we should prevent road kill or il-legally throw away trash for their habitat and their life
Please save us
Thank you very much
