New natural history note published documents hellbender yawns

Our recently published natural history note entitled, Observations of yawning behaviour in the eastern hellbender (Cryptobranchus alleganiensis alleganiensis), is the first published documentation of hellbenders yawning. These observations were made while filming hellbender behavior for a broader conservation-driven research project designed by Amber Pitt and Steve Davis (US Fish & Wildlife Service) and implemented by Sean Hartzell for his Master’s thesis research.
