NZ has the most bioluminescent limpets

NZ has the only freshwater bioluminescent limpet in the world.

When disturbed, these small (11mm long) limpets glow brighter than glow worms. They release a burst of glowing slime as a distraction for would-be predators.

Unique to New Zealand, it is only found in the North Island's streams and rivers. To see the limpets, visit the Opanuku Pipeline Track in Auckland at night – there is a beautiful campground right next to the stream.

If the limpet is disturbed while in the water, the slime floats away, but in this photo the slime is running down the rock.
