Today's beach find was a first for me: a 2 metre Blue shark (Prionace glauca). So much bigger than the sharks that usually wash up on Waikawa Beach.

Large dead shark with white belly and blue upper.

Also known as the blue whaler or blue pointer, the blue shark’s upper body is a striking cobalt blue and the underside is bright white. Their large black eyes have a protective membrane to shield it from struggling prey.
