The Hydrophis semperi, also known as the Lake Taal snake, is a very special and rare type of venomous sea snake. It lives only in one place: Lake Taal on the island of Luzon in the Philippines.
What makes this snake so unique? Most sea snakes live in the ocean. But the Lake Taal snake is one of only two known sea snake species that live almost entirely in freshwater! The other one is called Laticauda crockeri.

What's in a Name?
The scientific name, H. semperi, honors Carl Semper. He was a German ecologist who first discovered this snake in the mid-1800s. In the local language, people call this snake duhol matapang.
Snake Family Tree
The Lake Taal snake belongs to a group called "true" sea snakes. These are part of the Elapidae family, which includes many venomous snakes. This family also includes cobras and mambas.
What Does It Look Like?
Like other "true" sea snakes, the Lake Taal snake has a strong body and a small head. It has a special flattened, paddle-like tail. This tail helps it swim easily in the water.
This snake is quite short compared to other sea snakes. Adult snakes are usually about 50 to 70 centimeters (20 to 28 inches) long. Its body is often dark blue or black. It has thin yellow or white bands across its body. Its nostrils are on top of its head. They have special flaps that close to stop water from getting in when the snake dives.
Where It Lives and How It Evolved
The H. semperi lives only in Lake Taal in the Philippines. This lake used to be called Lake Bombon. It is the only freshwater sea snake found in the Philippines. It spends its whole life in the lake's slightly acidic waters. It finds food and reproduces there.
Lake Taal is actually a volcanic crater lake. Long ago, it was connected to the sea and had saltwater. But a volcanic eruption in the 1500s blocked it off from the ocean. Over time, the lake's water slowly became freshwater. This amazing change led to many ocean animals, including the Lake Taal snake, adapting to freshwater. This means the species is quite young, having lived in freshwater for less than 1,000 years.
What's on the Menu?
Just like other "true" sea snakes, the Lake Taal snake loves to eat fish. It hunts and eats the many different kinds of fish that live in Lake Taal's murky waters.
Life Cycle and Conservation
Scientists don't know much about the life cycle of the Lake Taal snake. We don't know how often they reproduce or how many there are. Because of this, it's hard to estimate their population.
The Lake Taal snake is considered vulnerable. This means it could be at risk of disappearing. Many animals that live only in one place, like this snake, are sensitive to changes in their environment.
The lake faces challenges from human activities. Pollution from nearby towns, businesses, and farms can harm the lake's water. There are also many fish farms in the lake. All these things can affect the snake's health and its home.
Even though the snake is not hunted for its commercial value, it sometimes faces danger from people. Fishermen who meet these snakes might kill them. This happens simply because some people are afraid of snakes, even though the Lake Taal snake is generally calm. Protecting Lake Taal is important for the future of this unique snake.
