Hannah Rainforth is a scientist she is interested in kakahi also known as black water mussels. She is from Whanganui river in NZ. Kakahi are one of the most threatened groups of animals worldwide. You might wonder why she wanted to study kakahi well she started researching and found out that they have nearly disappeared in the Whanganui river.
So she wanted to find more kakahi in NZ also find the remaining kakahi in the river. If there were very few or none juveniles the kakahi will end up extinct. The female kakahi releases tiny larvae into the ocean the larvae have to latch onto a fish or it will die. Kakahi can live for fifty years, you can see how old they are by counting the growth rings on its shell.
She caught 185 kakahi when Hannah moved up the river that's the most she has ever caught in her years of searching. Caring for our waterways will help kakahi and other fresh water animals can thrive.
