#WhiteSharks are ENDANGERED. Known for having a pointed snout and large, flat, triangular teeth, their body is stout and coloured grey or brownish grey on top and a white underbelly. The main dorsal fin and pectoral fins are black tipped. An adult can measure 3.8 to 6 meters.

"We found that white sharks might investigate surface objects by rotating their first dorsal fin on its axis towards the object. Our videos suggest that the dorsal fin in white sharks may have additional capabilities beyond being a stabilizing appendage."
