Half-eaten shark washes ashore on Florida beach

Some posted graphic photos of the shark on Instagram. Volusia County Beach Safety Ocean Rescue spokeswoman Tamra Marris said the shark appeared to be a blacktip or spinner shark.

"It is unknown what type of predator bit the dead shark or how far offshore it was," Marris said in a statement.

Thousands of blacktip sharks migrate to Florida waters each year to mate and eat.

While it's not uncommon to see sharks in the water, this photo is a powerful reminder that there's always a bigger predator out there.
