Tonna cumingii, also known as Cuming's tun, is a very large sea snail. It is a type of marine mollusc, which means it lives in the ocean and has a soft body, often protected by a shell. These snails belong to the family called Tonnidae, which are known as tun snails.

About Cuming's Tun Snail

Cuming's tun snails are part of a huge group of animals called Animalia. They are in the Mollusca phylum, which includes snails, clams, and octopuses. More specifically, they are gastropods, which means "stomach-foot." This refers to how their body and foot are arranged.

How Scientists Name Snails

Scientists give every living thing a special two-part name, like Tonna cumingii. This helps everyone around the world know exactly which animal they are talking about. Sometimes, scientists learn new things and change a snail's name or how it's grouped with other snails. This helps them understand how different species are related.

Where Cuming's Tun Snails Live

Cuming's tun snails are found in the ocean. They are often seen near the southern coasts of India and Sri Lanka.

Ocean Homes of the Tun Snail

Sometimes, snails that look very similar to Cuming's tun have been found in the waters around New Zealand and Australia. There have also been a few sightings in the Philippine waters. Scientists are still studying these snails to figure out their exact range. This means they want to know all the places where these snails live.

What Does a Cuming's Tun Shell Look Like?

The shell of a Cuming's tun snail can be quite large. It can grow up to 91 millimeters (about 3.6 inches) tall. The shell's width can be up to 66 millimeters (about 2.6 inches). These measurements show just how big these sea snails can get!
