Tucetona laticostata

Tucetona laticostata, or the large dog cockle, is a salt water clam or marine bivalve mollusc in the family Glycymerididae.

Despite the common name, it is not closely related to the common cockle. The word dog cockle implies that it roughly resembles a real cockle, but is not considered very good to eat, in other words, "only fit for dogs". Māori names include kuakua and kuhakuha.
