WATCH: Sea Turtle Feast On Giant Jellyfish Off Cape Cod Coast

PROVINCETOWN, MA — The Center for Coastal Studies captured rare footage of a leatherback sea turtle feasting on a massive lion's mane jellyfish.

The team from the humpback whale studies program spotted the turtle on Stellwagen Bank. Coastal Studies officials said the turtle was relatively small at 4-feet-long and weighing a few hundred pounds.

"Wow! This is definitely not something you get to see every day," Coastal Studies officials said in a Facebook post, but the group reiterated it's even rarer if the turtle's see us.

"While the turtle was feeding it was oblivious to the world around it, including approaching boats," officials said. "As with whales, boat strikes and entanglement in fishing gear are relatively common for this endangered species, so please keep a sharp look out for them."

Anyone who sees any entangled animals while on the water was asked to call the Center for Coastal Studies hotline at 1-800-900-3622.
