Preeti Desai of the National Audubon Society first discovered the animal and posted the photo on Twitter to see if anyone knew what it was.
It is suspected that Hurricane Harvey, which conveyed solid breezes and flooding to Texas, could clarify why the animal was cleaned up.
But it could also be another member of the snake-eel family, he explained.
The colossal creature was found rotting on a beach in Texas City after the megastorm which ravaged the southern US.
He said it might likewise be a garden or conger eel, since "each of the three of these species happen off Texas and have substantial tooth like teeth".
"I've already got a huge interest in wildlife, especially birds and ocean creatures, but it was so unexpected to see it there on the beach".
The fangtooth wind eel, otherwise called a "tusky" eel, is generally found in waters in the vicinity of 30 and 90 meters somewhere down in the western Atlantic sea.
Ms Desai told the BBC she was assessing the damage of Hurricane Harvey when she stumbled upon the eel.
"So I put the photos out there and the guesses started coming in".
She's excited by the coverage, but says there's no reason for people to be scared of the eel. "I thought it could be something from the deep sea that might have washed on to shore".
The snake-eel isn't the only thing washed up from the recent storms, two manatees washed up on the coast of Florida in the aftermath of Hurricane Irma.
