A Mexican national was arrested at Tokyo's Haneda Airport after customs officials found approximately 200 lizards concealed within 22 pairs of socks in his suitcase. The man arrived on a flight from South Korea on August 8.

During the inspection, authorities discovered the reptiles packed into socks inside the luggage. One lizard was found dead when the suitcase was opened. Among the discovered animals were nine Mexican alligator lizards, a species listed as endangered with international trade restrictions.

The 23-year-old man reportedly told investigators that he purchased the lizards in Mexico for approximately $3.50 to $4.70 each. In Japan, some of these reptiles can fetch prices around $630 apiece.

Former federal security director Keith Jeffries noted that financial incentives often drive unusual smuggling attempts. "If there's a market for it, people will attempt to smuggle it," Jeffries told Fox News Digital. "We've seen this before many times. It happens more frequently than any of us would like."

Airport screening procedures and priorities can differ among agencies. In the United States, for instance, the Transportation Security Administration (TSA) primarily focuses on detecting aviation security threats like weapons and explosives, rather than specifically searching for smuggled wildlife or drugs, according to Jeffries. "The TSA security directives do not look for items from just a smuggling standpoint," he explained. "They look for guns, knives, explosives, incendiary devices — and it's very specific and narrow to that."

However, wildlife smuggling is not uncommon. Jeffries recalled instances during his tenure involving exotic turtles and nearly 100 exotic birds found in checked luggage. In a separate incident that occurred weeks prior to the Tokyo discovery, U.S. Customs and Border Protection agriculture detector dogs alerted officers to a suitcase arriving from Thailand. That bag contained nearly 100 pounds of prohibited items, including raw meat, fruits, plants, and approximately 16 pounds of Bengal monitor lizard. The U.S. Fish and Wildlife Service took custody of the monitor lizard. CBP agriculture specialists examine international luggage for items that could introduce pests, animal diseases, or invasive species into the United States.
