Vertebrates

Is it true that snakes used to have legs?

Snakes used to wander the Earth on legs about 150 million years ago, before they shifted from strut to slither. Some snakes, such as pythons, retain tiny vestiges of legs in the form of two small bumps on either side of their pelvis.

What will you do on seeing a snake?

Leave it alone. Snakes are generally shy and will not attack unless provoked, so it’s best to leave them be. If you see a snake inside your home, get all people and pets out of the room immediately. Shut the door and fill the gap underneath with a towel, then call a professional snake catcher for assistance.

What to do if you see a snake in your house?

If you discover a snake in your house, act as soon as possible, for both the snake’s and your peace of mind:

  2. If possible, carefully open a nearby door and use a broom to gently herd the snake outside.

What should you do immediately after a snake bite?

If you suspect a snake bite:

  1. Immediately move away from the area where the bite occurred.
  2. Remove anything tight from around the bitten part of the body (e.g.: rings, anklets, bracelets) as these can cause harm if swelling occurs.
  3. Reassure the victim.
  4. Immobilize the person completely.

Can snakes smell?

Instead of nostrils, snakes smell with a special organ, called the Jacobson’s organ, on the roof of their mouths. Snakes use their tongues to grab chemicals (which smells are made of) from the environment.
