Video Study Explains Reedsnakes’ Rolling Escape

Name: __________________________ Date: __________________

Read the story

Multi-angle recordings revealed coordinated rolling in dwarf reedsnakes. Peak forward speed during this escape behaviour was approximately four times that recorded for lateral undulation.

The rear body rotated substantially while the head remained aligned with travel. This separation of movement may help preserve control at speed.

Read and practise

1. Which method revealed the movement?

   1. Videos from different directions
   2. Only pictures of motionless snakes
   3. Only measurements of old snake skins

2. Which observation concerns head position?

   1. They rotated as much as the back of the body
   2. They stayed facing forward as the body turned
   3. They always faced away from the direction of travel

Your turn

Separate the observed head position from the proposed benefit for control.
