The doctor, who has 4.1 million followers on the video streaming app shared the video explaining the occurrence which has since racked up more than 571k views
Since 2007, 21 feet have washed up on the shores of US and Canadian beaches, completely unattached from the bodies they once belonged to.
In Dr Karan Raj’s latest video, the doctor delved into the mystery of why the chopped-off feet were found on the shores of the Salish Sea between Canada and the US.
Dr Raj speculated on the reason as part of a “story time” segment on his TikTok channel, asking why the feet were still in shoes when they wash up onshore.
He hypothesized the cause, jokingly saying “was it because of a serial killer with a foot fetish?” or “was the mafia disposing of bodies so their enemies sleep with the fishes?”
He then reasoned that the instances occur due to scavengers and the footwear industry.
He spoke about his theory for the macabre phenomenon stating: “When a human corpse falls to the ocean floor, it’s quickly set upon by scavengers.
“These scavengers are lazy feeders and prefer to eat the softer parts of our bodies first.
“Some of the softest parts of us are the soft tissues and ligaments around our ankles.”
He said: “Over the last few decades, shoes have become more buoyant.
“As a result, we could be seeing more severed feet on our shores.”
Footwear’s buoyancy means that the dismembered limbs will be able to float for longer, and ultimately wash up on nearby shores to give someone a grisly shock.
The appendages aren’t the result of anything more sinister though, as the Coroners Service in British Columbia ruled out foul play in December 2017.
They ruled that the feet that wash ashore separated from their bodies have originated from people who were killed either in accidents or are victims of suicide.
The most recent discovery in these grim circumstances came in January 2019 when the foot of Antonio Neill was discovered.
DNA helped identify the limb which arrived at Jetty Island in Everett, Washington.
Mr Neill had gone missing three years prior, and was last seen in December 2016.
