About the Mudflat Top Shell
What Does It Look Like?
The mudflat top shell has a strong, cone-shaped shell. It can be anywhere from 11 mm to 32 mm long when it's fully grown. The shell is often black, with thin, wavy yellow lines running along it.
The top part of the shell, called the spire, is short. It has five turns, or whorls. The very last turn is big and round. It has three to six spiral ridges, called keels, on its back part. The center of the shell is solid, without a hole. If you look inside the shell's opening, it's smooth and shiny like silver.
Where Does It Live?
This common sea snail lives in estuaries, which are places where rivers meet the sea. It is found only in New Zealand. You can find it on the North Island, the South Island, and Stewart Island.
