1. Animals in Danger
In the water
Chapter 5

2. River Dolphins

3. baiji dolphin species
lives in the Yangtze (Chang Jiang) River in China
1950´s = 6,000 baijis
they hear very well and talk to other dolphins
in past they heard small ships and swam under

4. Dangers to the baiji
big ships on the river and other noisesare a danger
baiji´s hit head on big ships
towns and factories pollute the river making the water dirty and hard for the baiji to see
the construction of the Three Gorges Dam changed the habitat

5. Trying to help the baiji
in 1983 the Chinese stopped hunting river dolphins
built a special habitat in the river
it was expensive to build the habitat so to earn money the govermnet sold the “baiji” name. Results= baiji drink, baiji hotel, baiji shoes
only some of the money helped the dolphins

6. Did it help?
1990 = 200 baiji found in 2,000 kilometres of the Yangtze River
2004=2 found in the river by scientists
Succesful????? I think NO!!!!

7. River dolphins in the Ganges River in India and Bangladesh

8. Why are the river dolphins in the Ganges River in danger?
10% of the world´s population live near this river so it is very polluted
dolphins can´t move up and down the river because of dams
now= 4,000 river dolphins remain in the Ganges River BUT THEY ARE IN DANGER OF EXTINCTION!!!!!

9. Sea Dolphins

10. Sea Dolphins live in nearly every sea of the world
people eat their meat
hundreds of thousands die because they are caught in fishing nets
fishing takes away the sea dolphins food

11. Killer Whales (speciesi n dolphin family)
live years in sea but only 10 years in a zoo
they like cold water
their ONLY danger is humans!!
pollution goes to sea and kills the whales and whales eat polluted fish and get ill (sick)
hunting is a danger >> The Inuit of Alaska hunted killer whales in the past but only a small number
after, hunters from other countries with big ships came to hunt the killer whales

12. Blue Whales of Antartica

13. Blue whales Biggest whale in the world Live 90 years 1900 = 250,000
hunters killed 30,000
Today = 5,000 DANGER OF EXTINCTION

14. OTHER SPECIES OF WHALES
-other species of whales are disappearing
-most countries stopped killing whales but some still do
-it is hard to protect the whale far out in the big, big sea
