What is "trichomycteridae"

The Trichomycteridae are a family of catfishes ( order Siluriformes) commonly known as the pencil or parasitic catfishes. This family includes the infamous candiru fish, feared by some people for its alleged habit of entering into the urethra of humans. Another example of this fish is the "life monsefuano", which is considered a special and ritual dish of the north Peruvian cuisine.

This family is prohibited from being imported into various parts of the USA.
