The Kikuzato's brook snake (Opisthotropis kikuzatoi) is a special kind of snake. It's also known as the Kikuzato's stream snake. This snake belongs to the Colubridae family, which is a large group of snakes. It lives only in the Ryukyu Islands of Japan, making it endemic to that area. This means you won't find it naturally anywhere else in the world!

What's in a Name?
The snake's scientific name, kikuzatoi, honors a person named Kiyotasu Kikuzato. He was the one who first collected a sample of this snake. This sample is called the holotype and is very important for studying the species.
Where Does It Live?
The Kikuzato's brook snake lives on Kumejima Island. This island is part of the Okinawa Group in Japan. It's a small, specific area where these unique snakes can be found.
Home Sweet Home
This snake loves water! The Kikuzato's brook snake lives in flowing streams. You can find it in the hilly areas of Kumejima Island. Sadly, many of the places between these streams have been turned into farms. This makes it harder for the snakes to move around.
What Does It Eat?
The Kikuzato's brook snake has a varied diet. It enjoys eating earthworms and freshwater shrimp. It also hunts small freshwater fishes. Sometimes, it will eat tadpoles and even small frogs.
Reproduction
Kikuzato's brook snakes are oviparous. This means that the female snake lays eggs. The baby snakes hatch from these eggs.
Why Is It in Danger?
The Kikuzato's brook snake is listed as Critically Endangered. This means it's at a very high risk of disappearing forever. There are several reasons why this snake is in trouble.
Main Threats
One big problem is that these snakes can get caught by accident. This happens when people are fishing or trapping other animals. Another threat is water pollution. Chemicals and trash in the streams hurt the snakes and their food.
Introduced Predators
A major danger comes from animals that don't naturally live on the island. The American bullfrog (Lithobates catesbeianus) is a big problem. These bullfrogs were brought to Kumejima Island in 1953. They eat the Kikuzato's brook snakes, especially the younger ones. This has put a lot of pressure on the snake population.
Other Challenges
Because there are so few snakes left, they are also facing problems with inbreeding. This happens when animals that are too closely related have babies. It can lead to weaker snakes. Scientists have even seen some snakes with small differences, like uneven scales on their heads. These differences were not seen in the past.
