Found in brick hole by stones in Hatfields Beach. Slug or frog eggs?
Not the best pics, will retake in better light. Smooth ridges. 5.4cm
High tide mark
Kakahi, New Zealand Freshwater mussel
With a resident hermit crab inside
At first I thought some sort of platydoris (After realising it wasn't a flatworm!) since it is so flat, but looks like D. citrina can get like this.
