Hawaiian monk seals are endangered and closely monitored by NOAA scientists who are alarmed that the seals keep getting eels stuck really deep in their nostrils. Read the rest
1. Chinese man is constipated. 2. Chinese man remembers an old folk remedy. 3. Remedy involves inserting a live eel up your bum. 4. Chinse man goes to hospital.
Seems like a foregone conclusion that if you insert a live eel in your rectum, health problems will ensue! The slippery monster ate through part of the guy’s intestines and went for a swim. The man went to the hospital to have it removed.
I don’t really have to say anymore because here’s a video from Chinese news with a CGI reenactment of the whole fiasco. From the music, the little green cloud, and the gas mask it appears that Chinese news takes this to be a comedic episode. Just remember this the next time you go out for a nice unagi dinner.

This intense slow-motion video, depicting an electric eel jumping from a tank to zap a faux alligator head, accompanies a new scientific paper by Vanderbilt University biologist Kenneth Catania. From Nature:
Catania first spotted the behaviour during earlier laboratory experiments with electric eels (Electrophorus electricus), when they would leap upwards to attack a metal-rimmed net as he was trying to fish them out of their tanks. He analysed it by presenting the eels with carbon rods and aluminium plates at which they struck; the video’s plastic alligator, with its flashing light-emitting diodes that are powered by the eel’s electrocution, is his dramatic demonstration of the effect...
The behaviour allows eels to directly shock their opponents, rather than having their voltage dissipated by water.
It is the first time that this has been recorded in a research paper, Catania says — although he argues that his discovery supports a widely disbelieved observation made more than 200 years ago by the Prussian explorer and naturalist Alexander von Humboldt. In a paper published in 1807, von Humboldt recounted that he had seen South American native fishermen herding horses into a pool of electric eels; the eels would discharge themselves against the horses and could be fished safely when they were exhausted.
According to Catania, there are other mysteries of the electric eels left to be solved, like how it can electrocute another creature without zapping itself in the process.
A new study says that this small eel photographed by accident on a Caribbean coral reef is the first green fluorescent fish ever recorded. Read the rest
The biology behind the green glow of Japanese freshwater eels could lead to new tests for jaundice and liver problems. RIKEN research institute scientists determined that a substance found in bile, bilirubin, is what triggers a protein in the eel, called UnaG (after unagi), to glow. Turns out, the amount of bilirubin in humans is a good indicator of liver health. Using a synthetic version of UnaG, the scientists could measure the bilirubin in a blood sample based on its glow. A similar technique may also aid in the study of tumors. "An eel's glow could illuminate liver disease" (Science News) Read the rest
