#7: Manta Ray Enemy
Other sea creatures are not as friendly as that above-mentioned eel. This Reddit user once went skin diving in the Galapagos and had a creepy encounter with a manta ray. They were down in the water about 7 meters when they saw a huge manta ray chilling on the sea floor. This person was understandably intimidated, so they swam away. Turns out this encounter wasn’t over.
On their way back up to the surface, they turned around and noticed that the manta ray had moved. It had been following and tracking this person as they swam around! It seemed like this creature was aware of the storyteller’s presence because it stopped moving whenever they looked directly at it. They were immediately freaked out and knew the manta ray wasn’t a fan of them being around their habitat. They swam to the surface and got out of there as fast as possible!
