Signs of premonition in sharks? Sharks in egg cases can detect predators’ fields

Sharks have the ability to detect predators from day one.

A newly release study finds that sharks still encased in egg cases may have the ability to  detect predators’ electric fields, long before they hatch.

Ryan Kempster from the University of Western Australia and colleagues collected and monitored 11 bamboo shark embryo from the Underwater World and Daydream Island Resort aquaria in Queensland, Australia. Researchers were able to discover the shark embryos held the ability to detect electric fields in the lab created to mimic those of predators such as fish.  The team of shark experts said that the study definitively showed the young sharks, even within their egg cases, can sense electric fields that mimic a predator, and respond by reducing respiratory gill movements to avoid detection.
