The Diloma bicanaliculatum, often called the knobbed top shell, is a type of small sea snail. It is a marine gastropod mollusk. This means it's a snail that lives in the ocean and has a shell. It belongs to the Trochidae family, which are known as the top snails because of their cone-shaped shells. The shell of the knobbed top shell can be between 10 mm and 20 mm in size.

Where It Lives

This sea snail lives only in New Zealand. You can find it around the North Island, South Island, and Stewart Island. For a while, there was a special group called Diloma bicanaliculata Lenoir. This group was thought to live between Cook Strait and Stewart Island. However, this special group is no longer officially recognized by scientists.
