Antiguraleus mundus is a type of sea snail. It is a marine gastropod (a kind of snail or slug) and a mollusc. This species belongs to the family called Mangeliidae.
About the Shell
The shell of Antiguraleus mundus is quite small. It usually grows to about 7.5 millimeters (which is less than half an inch) long. Its widest part, or diameter, is around 3.2 millimeters.
The shell has an elongated, spindle-like shape. It is thin and can be quite fragile. Its color is white. The shell has a "turreted" look, meaning it has a tower-like spire.
Shell Patterns
The shell has interesting patterns called sculpture. These patterns include:
- Axial Ribs: These are narrow, rounded ridges that run along the shell from top to bottom, like ribs. There are about 16 of these ribs on the main body part of the shell. They are slightly slanted and almost continuous over the different sections of the shell.
- Spiral Lines: These ribs are crossed by thin lines that wrap around the shell in a spiral. There are several of these lines, some close together and some spaced out.
- Small Bumps: Where the axial ribs and spiral lines cross, they create tiny, oval-shaped bumps.
The main body of the shell is also smooth in front of the opening. The top part of the shell, called the spire, is tall and cone-shaped. It is about 1½ times taller than the shell's opening. The very first part of the shell, called the protoconch, is smooth and rounded.
The shell has six sections, or whorls, that get bigger as they go down. Each whorl has a high, sloping "shoulder." The opening of the shell is pear-shaped. It has a short, wide canal at the bottom, which is used for breathing.
Where It Lives
This sea snail lives in the ocean. It has been found off the coast of North Island in New Zealand, near a place called Flat Point. It lives quite deep underwater, at about 195 meters (around 640 feet).
