The Faint-banded sea snake is a species of snake known by the scientific name is Hydrophis belcheri. The snake is also known as Belcher's Sea Snake, and often are mistakenly called hooked-nose snake. Faint-banded sea snakes are the most poisonous snakes in the world. Two milligrams of its venom can kill a thousand people. The typical victims are fishermen. The bites from these snake are not painful, but medical cares have to be taken. The good news about this snake is that it seems to be quite friendly and mild-tempered, and if it does decide to bite, studies show that only 25% of the time will it release its venom.

These snakes are typically found in the area of India Ocean, around New Ginuea in the Philipines, this is the Visayan area and Panay. Another areas are Austraila, probably around Queensland or north territory. [2]

Body Design

a picture of the snake

Faint-banded snakes are not very long(50cm~100cm) and thin and have a flattened tails that are vertical. The color of body is yellowish tone. [3] Also, it has bands that are going across the body that are greenish tone. These greenish bands cover the head. it has a small mouth and a small head. One amazing thing is when the snake is not in water, its skin seems like yellow. The snake's tail helps the snake to swim well. The tail is like a paddle for the snake. The snake does not spend much time on land so that the snake is rarely seen on land. It breathes in air from the water. The snake has valves above the nostrils. The valves are closed when snake is under water. You may be surprised, but when the snake sleeps, it does not have to breathe for seven to eight hours. [4]

Life Cycle

The lifespan of the snake is only 4-5 years. The snake feeds on the small fish, squids, and Octopus. [5] Male sea snakes have two penises. Only one is used for mating. These are called hemipenes. [6]The mating of the snakes takes a long time. [7]. The snake live in warm waters so that mating is supported by the warm waters. For male snakes, they mate in their third years and for females, they mate in their fourth years or fifth years. The snake's maturity is not seasonal. Therefore, they can mate in every season unlike other sea snakes. The warm waters support their mating for every seasons. [8]


The map of the area where the snakes live

The snakes like to live in warm water. However, if the water gets too warm, they swim down to underwater. They are mostly found in tropical environments. The snakes can usually be found in tropical oceans, Indian Ocean, New Guinea, Gulf of Thailand, Indonesia, off the coast of the Philippines, and the Western Pacific Ocean. The size of half of the snake depends on how large the mother is. There are some predators such as sea eagles, sharks, large predatory fishes, eels, and etc. However, the snake usually does not get out of the water. Therefore, the snake has just a little chance to distinction. Therefore, they are able to live in lands or oceans.[9].


Usually, sea snakes are not considered to be aggressive. Faint-banded snakes are declared as the most poisonous snakes in the world. Couple milligrams of its venom can kill like a thousand people. Just a few of this snake's bite might have venom. [10] Usually, it does not release its venom. However, when the snake feels threatened, it releases its venom. Only about a quarter of the snake's bites will be venomous. [11] The snake is easy to control, so that the snake will attack rarely. Those who normally get bitten by these snakes are fishermen. The snake is caught by fishermen in their nets. However, the snake does not inject much of venom of them so that for those who get bitten, they are only poisoned 25 percent of the time. The snakes are very calm. The snake is not describes as the most dangerous snake by some snake-specialist. They describe the Indian Taipan snakes are the most dangerous snakes in the world. [12]

the type of the venom is neurotoxin so the venom affects the central nerve system. [13]Neurotoxins are chemical agents that affect the transmission of chemical signals between Neurons, causing a myriad of problems. Neurotoxin breaks down the muscle cells, red blood cells, and liver. [14]
