Danionella cerebrum has a pair of extrinsic, indirect sonic muscles that house the drumming cartilage. When a sonic muscle contracts, the fifth rib is pulled anteriorly and builds tension as it pulls the cartilage. The sudden release of the cartilage causes it to rapidly strike the swim bladder, producing a short, loud pulse. A burst of pulses is generated with either bilaterally alternating or unilateral muscle contractions. In sum, this mechanism enables loud and stereotyped sounds that can be elicited in structured sequences, making it a unique solution for acoustic communication and ultrafast skeletal motion in vertebrates surpassing the limitation of muscle contraction speed.
