The maximum size for this species is approximately 45 millimeters.

Habitat and Occurrence

Lima zealandica is a common inhabitant of the subtidal zone, generally found in depths ranging from 10 to 50 meters. It prefers habitats with soft substrates, such as sand, mud, or gravel. This species is endemic to New Zealand waters, where it is a common sight along the coastline, especially in the temperate waters of the continental shelf.

Taxonomy

Lima zealandica is classified as a bivalve mollusc, belonging to the Class Bivalvia. It is placed in the Order Limida, and the Family Limidae. These classifications reflect its specific characteristics and evolutionary relationships within the broader group of bivalves.

Feeding

Lima zealandica, like most bivalves, is a filter feeder. It utilizes its gills to draw in water, filtering out microscopic plankton and other organic matter for sustenance. This feeding strategy contributes to its role in the marine ecosystem, acting as a crucial link in the food chain.
