RESULTS Interdental distance increased from 28 mm (95% confidence interval, 25-30) in slight flexion to 46 mm (95% confidence interval, 42-49) at full extension. ...

Dynamics of Mouth Opening in Hydra.

Hydra, a simple freshwater animal famous for its regenerative capabilities, must tear a hole through its epithelial tissue each time it opens its mouth. The feeding response of Hydra has been well-characterized physiologically and is regarded as a classical model system for environmental chemical biology. However, due to a lack of in vivo labeling and imaging tools, the biomechanics of mouth op...
