Why are they so special?

These dolphins are endangered and very pink unlike other dolphins in the world. The rarer ones are very pink and born albino, meaning they have very pale glossy pink skin and red eyes. People who have seen them say that they are pinker than the South American Boto, they are very unique to Southeast Asia.

Pink Dolphins live… where?Where are they found?

The pink dolphin has different names due to the different geographical regions they live in. For example the Amazon river dolphin. They can be found from South Africa to Australia and up the Chinese coast although most dolphins like to live in the Orinoco river.

What endangers the dolphins?

Reclamation• Construction of the new airport at Chep

Lap Kok and the North Lantau Expressway have destroyed the natural coast and homes of many marine creatures.

• Toxic and contaminated mud from reclamation is dumped in the seabed just north of the new airport platform.

About 150,000 cubic meters of raw sewage is dumped into the western harbor area every day! Sewage includes household wastes such as

• cleaning fluids• Bacteria• and viruses • And industrial effluent.

These can affect the dolphins and harm them, industrial effluent.

A picture of sewage will be added on the sides of this slide.

Over-fishing

Over-fishing and boat pollution is really a big problem in Hong Kong. About 70 boats cross the harbour each day and this results in over-fishing and polluting the habitats in which the dolphins live in.

They are caught in nets a lot, and thrown back into the sea by the time they are already dead or injured.

How many dolphins are there now?

Estimates are fewer than 100 to around 150.

This is because there is an increase in

•poaching•landfills

• sea traffic. Since Chinese White Dolphins rarely stray far away from their habitat,

but the water pollution in Hong Kong has a high impact on them.Industrial, agricultural, and domestic sewage are amongst the threats to the dolphins. In the Pearl River Delta, about 190,000 cubic metres

of sewage is drained into the sea without any treatment daily.

What have we done to help them?

There are rules now that limit fishing to prevent over-fishing so Dolphins have enough to eat and they are not caught.

The pink Chinese White Dolphins are a rare sight now but we can pay attention to the rules so that we may not endanger them.
