Strictly Forbidden
It appears that there are still some people in this world who are unaware that it is against the law to bring any type of contraband onto an airplane, despite the fact that this information may appear obvious to some. Smuggling anything that is not native to a country onto an airplane is against the law. This includes animals, fish, and even exotic fruits.
This passenger attempted to smuggle not only this bag of eels into their carry-on luggage, but also 163 tropical fish and 22 invertebrates in addition to this bag of eels that they were trying to smuggle in. The suspicious bag of marine life specimens was turned over to the United States Fish and Wildlife Service.
