Conticosta petilinus is a type of sea snail. It's a marine gastropod, which means it's a kind of mollusk that lives in the ocean. This snail belongs to the Pseudomelatomidae family, often called "turrids and allies."
About the Conticosta Petilinus Shell
This sea snail has a shell that is about 12.5 millimeters (half an inch) long. Its widest part is about 4.6 millimeters across.
The shell is thin and looks a bit like a spear or a small tower. It feels smooth and shiny. The shell is mostly a buff-yellow color. It has two bands of a darker, reddish-brown color. One band is near the top of each spiral, and the other is around the middle.
The shell has 10 whorls, which are the turns of the spiral. The first two whorls are part of the "baby shell," called the protoconch.
The shell also has rounded ridges, or "ribs," running down it. There are about ten ribs on each whorl. These ribs don't always line up perfectly from one spiral to the next.
On the upper parts of the shell, the spiral lines are hard to see. They might just look like small bumps on the ribs. On the main, largest part of the shell, there are about fifteen faint, widely spaced spiral lines.
The opening of the shell, called the aperture, has a curved shape. The outer edge of the opening is simple and bends slightly inward. The siphonal canal, which is a small tube at the bottom of the shell, is short and curves a little.
Where Conticosta Petilinus Lives
This sea snail lives only in Australia. You can find it off the coast of New South Wales. This means it is endemic to that area.
