It's important to note that blue ribbon eels are venomous. They have a sharp, venomous spine on their dorsal fin, which they use to defend themselves against predators. However, they are not aggressive towards humans and are generally harmless.
Interesting fact: Blue ribbon eels are protandrous hermaphrodites, meaning they are born male but can transform into females later in life. This usually happens when they reach a certain size and age.
