Pink DolphinsPink Dolphinsby Candace Lau 8M

What are pink dolphins?Pink dolphin’s scientific name is sousa chinensis. Pink dolphins are commonly mistaken to be fish, but they are actually mammals, which means they are warm-blooded.

Pink dolphins feed near the shore where there is fish, crustaceans (such as crab and shrimp). There is some evidence that a pink dolphin is not born pink, but is affected by their diet, like pink flamingos.

What is their diet?

Pink dolphins prefer to live in places where salt water and fresh water mix together and in shallow waters like the coast of Australia, Indian Ocean coast of Africa or Hong Kong.

Where can they be found?

Why is the quality of HK waters worsening?

• Reclamation – creating land by filling the sea• People – people throw their rubbish in the

ocean• Sewage – poor sewage systems result in

unfiltered rubbish flowing straight into the sea

Reclamation, garbage in the sea and sewage all cause the loss of a natural and safe habitat for pink dolphins

How is it affecting pink dolphins?• Reclamation – this process decreases the size

of pink dolphins natural habitat• People – pink dolphins sometimes get tangled

in the rubbish which makes it harder for them to swim (they may get stranded)

• Sewage – polluting the waters will cause the dolphins to become sick

Look at the above image and think about how seriously the environment is really affecting pink dolphins…
