A majestic giant squid (Architeuthis) made the scene at Toyama Bay in central Japan. At an estimated 3.7 meters (12.1 feet), researchers think this was a juvenile.
"My curiosity was way bigger than fear, so I jumped into the water and go close to it," Diving Shop Kaiyu proprietor Akinobu Kimura told CNN.
"This squid was not damaged and looked lively, spurting ink and trying to entangle his tentacles around me. I guided the squid toward to the ocean, several hundred meters from the area it was found in, and it disappeared into the deep sea."
