A giant mysterious sea creature spotted in the turquoise waters of one of New Zealand's most idyllic bays is suspected of having caused an unexplained wake in the island country's ocean waters, Inquisitr reported.

The massive unexplained wake was captured by satellite at about 11.30 a.m. on January 30 in a Google Earth image of Oke Bay, in the Bay of Islands, an area on the east coast of the Far North District of the country's North Island.

The unusual wake could have occurred due to a sea creature around 40-feet long, Engineer Pita Witehira, who spotted the wake on Google Earth while researching for his holiday home, told Daily Mail Australia.

"I spotted it about a week ago," Witehira, from Hamilton, New Zealand, said. "We have some property near Oke Bay and I'm about to build a beach chalet up there, I zoomed down and found that. The Native Maori would call this a 'Taniwha' ('Troll') as it appears not to be a whale and it is far too big to be a shark.

"It is moving too fast and turning too sharply to be a whale. It's way too wide for a shark and way too long... It's got to have a lot of weight under the water to create that kind of drag."

Since motors are normally known to create white froth in the water, Witehira has ruled out the possibility of a boat having caused the rare wake, according to International Business Times.

The unusual sighting comes after an aerial photograph appeared in October, showing a giant crab that was at least 50-feet-wide lurking in shallow water in England.

While some believe it is proof that "Crabzilla" exists, others think it's a sandbank shaped like a crab in the seaside town of Kent, or maybe just a playful hoax.

Oke Bay, a white sand beach with shallow water of about 50-feet-wide which suddenly drops into the bay, is known to have abundant undergrowth in the deeper sections of the bay.
