Antiguraleus costatus is a type of small sea snail. It is a marine gastropod, which means it's a kind of mollusk that lives in the ocean. This snail belongs to the family called Mangeliidae.
Naming the Snail
Scientists give every living thing a special name. For this snail, its scientific name is Antiguraleus costatus. Sometimes, different scientists might use slightly different names for the same animal. This can happen when they are still learning about a species. For example, some experts also know this snail as Guraleus wilesianus.
What Does It Look Like?
The shell of Antiguraleus costatus is quite small. It can grow up to about 10 mm long, which is about the length of a fingernail. Its width is around 3 mm.
The shell is thin and has an oval shape that is longer than it is wide. It's usually a pale cream color. Sometimes, it might have one or two faint, narrow buff-colored bands.
The shell has six whorls, which are the spiral turns of the shell. The top two whorls are very smooth and shiny. The shell has narrow, sharp ridges that stick out. These ridges are called "riblets." They become closer together and smaller as the snail grows. They disappear towards the bottom of the shell. The first full whorl has about sixteen riblets, and the largest whorl can have around twenty-seven.
The bottom part of the shell has about ten fine, spiraling lines carved into it. The opening of the shell, called the aperture, is wide. The edge of the opening, known as the outer lip, is thin. It has a wide, shallow dip or curve called a "sinus."
Where Does It Live?
This marine snail lives only in Australia. You can find it off the coast of New South Wales.
