| Scientific classification |
Anacithara brevicostata is a type of sea snail. It is a small mollusk that lives in the ocean. This snail belongs to a group of animals called gastropods, which are known for their shells. It is part of the Horaiclavidae family.
What it Looks Like
The shell of the Anacithara brevicostata is quite small. It is about 4.5 millimeters (mm) long and 2 mm wide. That's less than half a centimeter!
Shell Features
The shell is thin and shaped like a long oval. It has a light, pale buff color. There is also a thin band of color just below the top edge of each spiral.
The shell has six rounded whorls, which are the spiral turns of the shell. The first two whorls are called the protoconch. These early whorls are smooth and slightly tilted.
Ribs and Spirals
The shell has noticeable ribs that stick out a bit. These ribs are rounded and wider than the spaces between them. There are usually nine ribs on the second-to-last whorl. The main body whorl, which is the largest part of the shell, has ten ribs.
These ribs start at the top of each spiral and end suddenly near the outer edge. The shell also has many even, rough, and closely packed spiral lines. These lines cover the entire shell.
Opening and Other Parts
The opening of the shell, called the aperture, is wide and smooth. There is a small ridge called a varix. The snail's siphonal canal, which is a tube used for breathing, is just a small notch.
Where it Lives
This marine snail lives in the ocean. It is endemic to Australia, meaning it is found only there. You can find Anacithara brevicostata off the coast of Queensland, a state in northeastern Australia.
