I keep finding lots of 'factoids' such as:
The Devilfish is another name for the Japanese delicacy tako, which is a poisonous fish which will kill if eaten without proper preparation.
Which is just completely incorrect. The poisonous fish is the
fugu, the blow fish.
Tako is Japanese for octopus, and the ones that are eaten aren't poisonous.
It's amazing how these things become accepted as accurate. Even the wikipedia page for
Dave Ulliott is incorrect.
