“Folks with the National Oceanic and Atmospheric Administration (NOAA) spotted what looks like a lazy attempt at a narwhal disguise on a juvenile Hawaiian monk seal in the Northwestern Hawaiian Islands. A blog post explains that while NOAA only started seeing seals with morays in their muzzles a few years ago, they've now spotted such schnoz shenanigans on several separate occasions. This might just be because scientists are doing more efficient seal-peeping than they did in previous decades, but it's possible they're witnessing the signs of some strange teen trend in the seal world...(Don't judge them; humans have put eels in worse places.)
And sure enough a case report from the Department of Surgery at the Kwong Wah Hospital in Hong Kong in 2004: “a 50-year-old man was seen at the Accident and Emergency Department because of abdominal pain.Physical examination revealed peritonitis.A shadow of an eel was notice on the abdominal radiograph.On further questioning, the patient admitted an eel was inserted into the rectum in an attempt to relieve constipation.”
I call BS on that.
Back to the article, “Emergency laparotomy found a 50 cm-long eel biting the splenic flexure of the colon and a 3-cm perforation was found over the anterior wall of the rectum...the patient was discharged home on day 7.
