Cuttlefish Hold Their Breath to Avoid Sharks
Breath-holding hides from Sharks bio-electrical sense.
But a new study by Dr. Christine Bedore, an Assistant Professor of Biology at Georgia Southern University, has found that cuttlefish have an additional strategy to hide from predators, including sharks.
By holding their breath, they stop generating the bioelectric field created by their respiratory system. With this so-called 'freezing' behaviour, the cuttlefish becomes invisible to the electro-reception used by sharks to find prey.
