HOW DO SNAKES MOVE?

Saturday - June 23, 2018 10:26 am , Category : Fun Facts

WTN- Snakes may lack arms  and legs, but their supple bodies squeeze through narrow opening and slither –a motion that depends on the combination of a flexible spinal column, strong muscles, and specialized scales on their undersides called scutes .

Adult humans have 26 vertebrae in their spines, a snake may have more than 400. Each pair of ribs is attached to a vertebra. Overlapping scutes on the snake’s belly attach by muscles to the animal’s ribs.

When the snake is moving , the back edges of the scutes catch and hold the ground as the muscles pull the snake forward . Snakes move according to the terrain they travel through side winding  snakes in sandy habitats have ways to keep from slipping , the snake swings its head and upper body forward and sideways. Its lower body and tail follow, with the belly raised above the hot sand leaving a j-shaped pattern in the sand.

Some snakes climb trees to do that, a snake coils up like an accordion anchors with its tail, then stretches its head forward ,gathering momentum so the rest of the body catches up.
