| Scientific classification |
Anacithara tumida is a tiny species of sea snail that lives in the ocean. It is a type of gastropod, which means it's a mollusk that usually has a shell and moves on a "foot." This particular snail belongs to the family Horaiclavidae. It was first described by a scientist named Charles Hedley in 1922.
About the Shell
The shell of Anacithara tumida is quite small. It is usually about 5.3 millimeters (which is less than a quarter of an inch) long. The shell is shaped like an oval and is very thin.
Shell Colors and Patterns
The shell is usually a plain white color. Sometimes, it can have thin, yellowish-brown lines that spiral around it.
Shell Structure
The shell has six puffy, rounded sections called whorls. The very first part of the shell, called the protoconch, is smooth and looks a bit like a flat disc. It tilts to one side and sticks out over the next part of the shell.
The shell also has broad, rounded bumps called ribs. These ribs are spaced out nicely and don't line up perfectly from one whorl to the next. There are usually nine of these ribs on the second-to-last whorl, and they gradually fade away towards the bottom of the shell. Both the ribs and the spaces between them are covered with many fine, spiraling lines.
The Opening
The opening of the shell, called the aperture, is wide. The edge of this opening, known as the lip, is simple and smooth.
Where It Lives
This sea snail lives only in Australia. You can find it off the coast of Queensland, which is a state in northeastern Australia. When an animal lives only in one specific place, it is called endemic to that area.
