The Daphnella sigmastoma is a type of sea snail. It's a marine gastropod (which means "stomach-foot") mollusk that belongs to the family called Raphitomidae. This snail was first described by a scientist named Hedley in 1922.
What Does the Daphnella sigmastoma Look Like?
The shell of the Daphnella sigmastoma snail is quite small. It usually grows to about 8.5 millimeters long. That's less than one centimeter! The widest part of its shell is around 3 millimeters across.
The shell has a long, somewhat spindle-like shape. Its color is usually a pale yellow all over, but the very tip, called the apex, might be a buff (light brownish-yellow) color. The shell has ten rounded whorls, which are the spiral turns that make up the snail's shell.
If you look closely, you might see narrow, curved ridges on the shell. These are called radials. There are also thin, close-set spiral lines that go around the shell. The opening of the shell, called the aperture, has a strong, wide edge. Inside the opening, near the outer lip, there are two small tooth-like bumps.
Where Does the Daphnella sigmastoma Live?
This sea snail is found only in Australia. It lives in the ocean waters off the coast of Queensland, which is a state in northeastern Australia.
