Amphibola crenata

Amphibola crenata is a species of air-breathing sea snail, a marine gastropod mollusk in the family Amphibolidae. This species is endemic to New Zealand, where it is commonly known as the "New Zealand Mud Snail."

Description

The Amphibola crenata has a shell that is typically 20-30mm in length, although larger specimens have been found. The shell is globular in shape, with a short spire and a large body whorl. The color of the shell is typically a dull brown or grey, often with darker spiral bands.

Habitat and Distribution

The Amphibola crenata is found in estuarine habitats, particularly in areas with muddy substrates. It is tolerant of a wide range of salinities and can survive in both fully marine and freshwater conditions. The species is most commonly found in the intertidal zone, but can also be found in subtidal areas.

Behavior and Ecology

The Amphibola crenata is a detritivore, feeding on organic matter in the mud. It is also known to be a facultative air-breather, meaning it can breathe air when necessary, such as during low tide when it is exposed to the air. The species is also known to be semelparous, meaning it reproduces once and then dies.

Conservation Status

The Amphibola crenata is not currently considered to be at risk. However, like all species, it is potentially threatened by habitat loss and pollution.
