What you see

Recorded on 14 August 2014. This loop is the whole 0:17 recording.

Points to check against your own sample:

  • Long cylinder, many times longer than wide, with a long row of membranelles along the front part.
  • Contracts in a fraction of a second to a fraction of its length, then slowly stretches out.
