Adult snakes on the list of the most beautiful snakes in the world are 3.3 to 5.2 in length.  However, some snakes grow up to 6 feet long.  The eyes of this snake are generally larger than other snakes and its head is oval.  Male snakes are usually light green or black in color.  But adult female snakes are brown in color.

When this snake is in danger, it adopts a strategy for self-defense.  When it sees an enemy, this snake inflates its neck in self-defense and can attack when it shows dark skin between the scales.  Although this snake rarely raises its hood, its hoods are set in such a way that it can strike well in front of the mouth.  This species of snake is not commonly found in Bangladesh.  Because the environment and climate of Bangladesh is not suitable for the snake to live.  Boomslang snakes have much stronger venom in their fangs.  This poison starts reacting very slowly but effectively in the victim's body.

In the wild, these dangerous snakes can live up to 8 years and are very harmless.  They do not attack anyone easily;  But if he attacks, his chances of survival are very low.

Normally a crocodile can live up to 35-75 years old, you will be surprised to know that they grow 4000 teeth in their lifetime.  But their jaws have 60-110 teeth.  There are certain teeth which are always fixed and always do some important work.  All those teeth are in standby mode anyway.  However, small teeth fall out after a certain period of time.  In this way, their teeth fall out and grow again about 50 times in their entire life.

Their jaws exert 5000 pounds or 2268 kg of pressure per square inch.  Because of this, anything that enters the crocodile's jaws does not come out easily.  And if it ever comes out, it must come out in two pieces.  The bite of crocodile teeth is stronger than the bite of shark teeth.  Their tails are also very strong and they strike with their tails.  There are slight differences between crocodiles and alligators.

Crocodiles do not sweat at all.  They used different methods to keep their body cool.  If you see crocodiles in real life or if you see pictures of crocodiles, you will almost always see them smiling.  The reason for being like this is that the method of keeping the mouth open to keep one's body cool is called mouth gaping.  It may seem angry.  But they open their mouths like this and release heat from the body and sleep.
