#3049 - Paphies elongata - Elongate Wedge Shell

At least the one on the right is - the larger one on the left is either Latona or Donax, in the Donacidae - not even the same Family as the Paphies.

AKA Shining Wedge Shell, Amesodesma perfuga, Mesodesma nitida, Mesodesma elongata, Mesodesma angusta, Donacilla angusta and Amesodesma angusta. Often called Pipis here in Australia, although the proper bearer of that common name, Paphies australis, is endemic to New Zealand.

Edible, saltwater, clams from intertidal sandy shores. Some species are highly valued foodstuffs.

#2637 - Paphies donacina - Southern Tuatua 

One of a genus of large edible beach-dwelling bivalves endemic to Aotearoa. Other include the pipi (P. australis), tuatua (P. subtriangulata) and toheroa (P. ventricosa).

The later was and is a traditional food for Māori, with wars fought over access to the best beds, and the shellfish transported around the country in bags made from southern bull kelp (Durvillaea poha).

Toheroa soup became an international delicacy after the Royal Tour of Prince Edward in 1920, but since 1979 harvesting has been mostly banned. To little effect - illegal poaching, poorly policed customary harvesting, vehicle driving on beaches, pollution, reduction in fresh water coming onto beaches, and disease, have all prevented a recovery in the bivalve's population.

#2417 - Paphies subtriangulata - Tuatua

AKA Erycina subangulata, Mactra subtriangulata, Mesodesma cuneata, reentsii, and spissa and Paphies porrecta.

A beach-dwelling Mesodesmatid bivalve, endemic to the islands of Aotearoa, where it was and still is widely collected for food. These days there are strict bag limits on how many you dig out of the sand.

The large shell is asymmetrical, with the hinge at one side. Its closest relative, the pipi (Paphies australis), has a symmetrical shell.
