AMAGANSETT - A young, dead shark that washed up on an East End beach earlier this week was a great white, according to an expert.

The shark washed up on an Amagansett beach on Tuesday. It was 4 feet long and weighed about 75 pounds.

An assistant professor of marine science at Stony Brook University, who performed a dissection on the creature, confirms that it was indeed a great white shark.

It's unclear what caused the shark's death.
