DSC_7652 Basket shell (Corbula zealanica) a tiny species distinguished by the left valve being slightly smaller, and 'nestled' within the margins of the right valve. Often abundant, particularly in the north. Shallowly buried in sandy mud or silty sand, in sheltered waters. Goat Island Marine Reserve, Leigh
DSC_0781 Wrinkled rock borer (Hiatella sp.) showing orange siphons and deformed shell. Found in the abandoned burrows of piddocks in mudstone and sandstone reefs. As it doesn't construct these burrows itself the valves may become distorted as the animal grows within an imperfectly confined space. Moeraki
