A type of dolphin called Hector's dolphins are found only around New Zealand and they are the most endangered sea dolphins in the world.
In the past 40 years their population has dropped from 30,000 to 7,000.
The reason for this rapid decline in population is the use of gillnets by commercial fishers.
These types of nets catch sea birds, turtles, dolphins and many other types of fish that they aren't even trying to catch.
All of these other creatures are simply killed and thrown overboard!
"An annual loss of this size will wipe out 62% of the population by 2050. Only a scattering of animals will survive, potentially pushing the population beyond the point of no return.
Absolute protection against commercial and recreational gill-netting and trawling is the only way to prevent their demise."
You hear that commercial fishing industry??
Save the dolphins!
