What are the habits of sea snakes in the ocean?

Chinese: Sea snakes are a type of venomous snake that lives in seawater all their lives. Sea snakes have valves that open and close their nostrils facing upwards, and when they inhale air, they close their nostrils and dive for up to 10 minutes.

The surface of the body is covered with scales, and under the scales is a thick **, which prevents the infiltration of seawater and the loss of body fluids. The salt glands under the tongue have the function of excreting excess salt that enters the body with food.

The body length of the small sea snake is half a meter, and the sea snake can reach about 3 meters. They inhabit coastal waters, especially in brackish water estuaries, and feed on fish. Except for a very small number of sea snakes that lay eggs, the rest are born and are ovoviviparous.

There are 19 species of sea snakes in China, which are widely distributed in the coastal waters of Guangdong, Guangxi, Fujian, Taiwan, Zhejiang, Shandong, Liaoning and other provinces.

Common ones are the blue-ringed sea snake, the flat-chin sea snake and the long-snouted sea snake. The sea snake can be used medicinally, and has the effects of dispelling wind and relieving pain, invigorating blood circulation, and nourishing and strengthening the body.

Global: Sea serpents.

Introduction There are about 50 species of sea snakes in the world's oceans, and about 20 species of China's coastal products. Sea snakes are a type of living reptiles, and together with turtles and turtles, they have become ancient reptiles that continue to this day.

The sea snake and the snake on land were originally one family, but due to changes in the environment, they moved to the sea to settle down. The tail of the sea serpent has become a flat oar-like in order to adapt to life in the sea, and its soft and slender body bends forward like a wave, swimming freely in the water. Sea snakes have small heads and often swim with their heads out of the water to breathe.

It has valves in its nostrils that close on its own, and closing the valves during a dive prevents seawater from rushing into the nasal passages. Sea snakes also have sharp teeth and are ready to strike.

Sea snakes are venomous snakes, their sharp teeth and venom that can numb each other and swallow them. The sea serpent's fangs make it invincible and domineering in the sea. The sea snake is an ovoviviparous animal, and during the breeding period, the eggs conceived by the sea snake develop into a baby snake in the mother's body, so the baby snake can move freely as soon as it is born.

Sea snakes are very capable of diving. The sea snake stays on the surface of the water for a short time, each dive is tens of meters deep, and the dive time is as long as dozens of minutes, what is the reason why the sea snake stores a large amount of oxygen for diving in such a short time? It remains a mystery to this day.

However, some people believe that the sea snake has a very large capacity of lungs, and during the dive, it can regulate various important organs, reduce oxygen consumption, and its ** can help breathing, and can quickly convert the oxygen obtained, to maintain the needs of the body when diving. It seems that the mystery of the sea serpent's dive has yet to be confirmed.

The sea snake is a type of reptile.

Sea snakes are a subfamily of the family Cobraidae of the Ophiidae family. Similar to the cobra subfamily, both are venomous snakes with anterior groove teeth. The tail is as flat as an oar, and the back of the trunk is slightly flattened.

There are 13 genera and 38 species in this subfamily. It is found in the warm water oceans from the Persian Gulf in the west to Japan in the east and Australia in the south, but there are no sea snakes in the Atlantic Ocean.

Sea snakes are also called"Blue ringed sea snake"，"Spotted sea snakes", which is a reptile that lives in the ocean. Poisonous. Long meters. Its torso is slightly cylindrical, with an elongated body, a flattened posterior end and a tail, and a dark gray back.

The sea snake is a type of reptile.

Sea snakes belong to the phylum Chordates.

Reptiles, Cobraidae.

Sea snakes prefer to live in shallow waters and often live together in groups. There are two types of sea snakes: one is to live in the ocean for life, and the mother snake gives birth to baby snakes in the body, and the baby snakes can move on their own after birth; Another type of sea snake swims to the beach to lay eggs during the reproductive season, and the eggs are hatched by sunlight to produce baby snakes, this type of sea snake is an amphibian.

Habits

Sea snakes like to be on the continental shelf.

It inhabits shallow waters around the island, and is rare in open waters with a depth of more than 100 meters. Some of them prefer to stay in muddy water with sandy or muddy bottoms, while others prefer to be active in the clear water around coral reefs.

Sea snakes dive at different depths, some are deeper, some are shallower. Shallow sea snakes generally dive for no more than 30 minutes, and stay on the surface for a short time, each time just showing their heads, and quickly take a breath before diving back into the water.

Deep-water sea snakes stay on the surface for a long time, especially in the evening and at night, and are reluctant to leave the water. They can dive for up to 2-3 hours.
