From: Bite force in the horned frog (Ceratophrys cranwelli) with implications for extinct giant frogs

An individual Ceratophrys cranwelli biting a force transducer. Leather strips glued to ends of bite bars provide a natural surface that encourages high-effort biting and avoids damage to teeth and bones. The strips also indicate a bite point for standardization of bite-force performance (see Methods).
