Botelloides is a group of small sea snails. They are also called gastropods or mollusks. These snails live in the ocean. They belong to the family called Trochidae, which are often known as top snails.
What They Look Like
Snails in the Botelloides group have special features. Their shells are shaped like a cylinder or a small pupa. This means they are somewhat long and narrow.
Shell Features
- The shell's whorls (the spirals) twist at an angle. This happens on the bottom two-thirds of the shell.
- The early parts of the shell are smooth. Later parts have fine, carved spiral lines. This is called the shell's sculpture.
- The opening of the shell, called the aperture, can be pear-shaped or round.
- Inside the shell, there is a central pillar called the columella. It has a hollowed-out shape.
- The outer lip of the shell has grooves inside. It also has a sharp, angled edge.
Some Botelloides species have shells that get wider towards the main body whorl. Others have shells that stay the same width, like a perfect cylinder.
Where They Live
Snails from the Botelloides group are found only in Australia. This means they are endemic to Australia. You can find them in the waters off many Australian states. These include New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria, and Western Australia.
