Previously it was known that Mature sharks use sensitive detectors to detect electric fields, which creates probable production

On the basis of information from cutaneous receptors, the brain data of creatures form the idea of the size, shape and velocity of the moving object hunting. Scientists from the Institute of Western Australia conducted a series of experiments with korichnevami cat shark (Chiloscyllium punctatum), which belong to the group of oviparous (also among sharks distributed inter alia, eiaiioeoa and a live birth). Marine biologists have collected eggs of future predators and removed them from the top protective shell. Therefore, the researchers were able to monitor what is done with the embryo inside the egg.
