Let’s know first about Which snakes live in the sea? After that we will discuss about folding fangs of snake and about is the Adder.
Which snakes live in the sea?
There is one group of snakes that is so well adapted for life in the sea that most of them never leave it. If you caught a sea snake and placed it on the ground it would flop around and show no sign of the efficient slithering of its land relatives.
In the water, however, sea snakes are excellent swimmers. Their bodies are flattened from side to side towards the rear end, and the tail is often paddle-shaped to help drive the snake forward.
Other adaptations of the sea snakes include nostrils on the top of the head and valves in the nostrils which prevent the entry of water when the snake is diving.
Sea snakes are extremely venomous but surprisingly they are among the least aggressive of poisonous snakes. They are particularly fond of eels which succumb within seconds to their venom.
The quick-acting venom presumably prevents the prey escaping into awkward holes and crevices once it has been bitten. Seasnakes rarely bite man and fishermen disentangle them from their nets by hand with little fear.
Which snakes have folding fangs?
The snakes with the most advanced venom injection system are those with folding fangs-the vipers and rattlesnakes. These snakes have large venom glands and long fangs which are folded into the mouth when not in use.
When about to strike, the snake erects its fangs and then plunges them deep into its victim. Unlike other venomous snakes which hang on to their prey, the viper immediately withdraws its fangs and waits for the deadly venom to do its work.
In a short time, depending on the size of the prey, the animal dies. Because they have such an effective striking action, vipers do not bother to pursue their prey. They merely lie in wait for a victim and then trail it for the short distance it manages to cover after being bitten.
How dangerous is the Adder?
Unless you are a young child, you need have no real fears about the effects of an adder bite. Adders are vipers and so have efficient venom, but it is only really effective on small prey- lizards, mice and shrews.Adders rarely bite humans unless they are frightened by being trodden on or deliberately provoked.
Many people try to kill them on sight but this is hardly necessary for they are actually quite useful in killing rodents. If someone is unlucky enough to be bitten, he may feel ill for a day or two but the chances are he will recover.
