Sharks VR (Virtual Reality)

Sharks are ancient cartilaginous fish -- Chondrichthyes -- is most close with rays (Elasmobranchii). Their skins are covered with enamel covered teeth-like structure. Or rather, their teeth are modified skin covered with placoid scales. Instead of gill flaps, sharks have gill slits out from which the water from mouth flows. Having no swim bladder, their asymmetrical caudal fin helps them go upwards in the water.
