Mitromorpha substriata is a type of sea snail. It's a marine gastropod mollusk that belongs to the family Mitromorphidae. These small snails live in the ocean.
About the Shell
The shell of Mitromorpha substriata is quite small. It usually grows to about 5.5 millimeters (which is less than a quarter of an inch) long. Its widest part, or diameter, is about 2.25 millimeters.
Shell Features
This snail has a small, thin, and delicate shell. It's mostly white, but its very tip, called the apex, is a pretty violet color. The shell has many fine lines that spiral around it. These lines are delicate and cover most of the shell's surface.
The very first part of the shell that the snail grew, called the protoconch, is smooth and round. The shell has about six whorls, which are like the turns of a spiral staircase. Each whorl gets a bit bigger as it goes down.
The opening of the shell, called the aperture, is shaped a bit like a diamond. At the bottom, it has a very short, wide siphonal canal. The outer edge of the opening is smooth and slightly thicker on the inside.
Where It Lives
This marine snail is endemic to New Zealand. This means it is found naturally only in New Zealand and nowhere else in the world. You can find Mitromorpha substriata living off the coast of Foyaux Strait, which is near the North Island of New Zealand.
