| Scientific classification |
Anacithara hervieri is a type of sea snail. It's a marine gastropod (which means "stomach-foot") mollusk that belongs to the family Horaiclavidae. This small snail was first described by Charles Hedley in 1922.
What Does It Look Like?
This small sea snail has a shell that is about 5 mm long and 2 mm wide. That's about the size of a grain of rice! Its shell is shaped like a tower, which scientists call "turreted." The main part of the shell is a dull white color. The very first part of its shell, called the protoconch, is a light yellow, like a primrose flower.
The shell has six spirals, or "whorls," that stack up. It also has low, raised lines called "ribs" that go straight down the shell. These ribs are angled near the top, like a shoulder, and don't connect between the different spirals. There are usually seven ribs on the second-to-last spiral.
Besides the ribs, the shell also has very thin, widely spaced spiral lines. Some of these lines are even finer. The largest spiral lines appear about twelve times on the last spiral and four times on the second-to-last spiral.
The opening of the shell, called the "aperture," is quite open. It has a small bump, or "tubercle," on each side of a wide, shallow curve called the "sinus." The shell also has a well-formed "varix" (a thickened rib). The "siphonal canal," which is a small groove where the snail's breathing tube comes out, is just a small notch.
Where Does It Live?
This marine snail is endemic to Australia. This means it is only found there and nowhere else in the world! You can find Anacithara hervieri off the coast of Queensland, Australia.
