Koura can be found in lakes and streams throughout New Zealand and are masters at blending into their environment, making them very hard to spot in the wild.
Koura have five pairs of legs however the first pair are pincers and not used for walking. They wave these pincers around to capture food, fight with each other and to ward off predators.
If frightened, they flick their tail forward hard and fast, scooting backwards out of trouble.
A female Koura can carry between 20-200 eggs, under the side flaps on her abdomen and the hatchlings cling to her underside with their tiny pincers for several months until the reach about 4mm when they finally leave home.
An adult Koura can reach 70-80mm depending on the species.
