Ever wondered how sharks communicate? They can't generate sounds so how do they do it? If you watch this video carefully you can see a grey reef shark using its body....exaggerated turns, slight hunching of its back, lowered pectoral fins. All signals to warn off potential predators, competitors or divers coming too close 💥 most interestingly is that these agonistic displays are quite common across many species suggesting they are used for interspecific communication....which species have you seen display such behaviours ?
Great video by shark behaviour expert @johann_mourier during a fish count survey in Fakarava, French Polynesia
