Other behaviours and adaptations
When disturbed, the Draughtboard Shark can increase its body size by inflating its stomach with air or water.
Females lay distinctive flask-shaped egg cases that have 19 to 27 strong transverse ridges. The egg cases are laid on the bottom where the tendrils attach to bottom-dwelling invertebrates and seaweed.
