Katharine the great white shark is closing in on the Space Coast again.

And this time, scientists suspect she might be pregnant, according to Florida Today.

Back in mid-March, Katharine's transmitter "pinged" in offshore waters east of Norfolk-Virginia Beach. She has swam southward since, reaching South Carolina by mid-April.

Then Sunday, Katharine pinged near the Florida-Georgia border. At 7:01 a.m. Wednesday, she pinged between Daytona Beach and Palm Coast.

"The first two years of her track, (she was) looking like an immature animal. And then this past year, she did not return to Cape Cod. So we're wondering if we're actually witnessing her transition from an immature shark to a mature shark — and wondering if she could be pregnant," said Chris Fischer, founder of the shark-tracking group OCEARCH.

"I have no idea where she's going right now. It'll be interesting to me to see if she returns to Cape Cod this fall, which would repeat the 2-year migratory cycle we've seen of mature females that have given birth in other areas of the world," Fischer said.

"She's an interesting shark, for sure," she said.

OCEARCH researchers captured Katharine during an August 2013 expedition off of Cape Cod and attached a satellite transmitter to her dorsal fin. At the time, she measured 14 feet, 2 inches long and weighed in at 2,300 pounds.

In 2014, Katharine became OCEARCH's first Atlantic great white shark to migrate past the Florida Keys into the Gulf of Mexico. Then she returned to Cape Cod, a suspected great white shark breeding ground.
