The eels were being shipped to Korea for consumption, according to police.
That truck wass unable to stop and turned over on Highway 101 in OR, and four other vehicles crashed into the containers of fish OR each other, KPTV reports.
Unfortunately for the owner of this auto, the eels secrete a slime when they are stressed.
Luckily only one driver was slightly injured from the crash.
The 3,400kg of hagfish were to be exported to South Korea, where they are considered a delicacy. Then all the other containers separated from the truck too and spilled onto the road.
How slimey are the sea creatures? The reason for their rather disgusting name is that the fish secrete slime when they are distressed, hence the nickname "slime eels".
In another picture, the state police tweeted: "In this heat.what is this going to start smelling like in the next few days?"
The truck was carrying 7,500 pounds of slithering fish in 13 different containers and the shift of weight caused one of them to come off the truck and "fly across the highway", police said.
Cars were left covered in slime following the accident, and photos from the local fire department showed eels on wheels.
A truck carrying eels turned over on a busy highway in OR, covering another vehicle and the roadway in slime. Although they look heartless, they actually have four hearts, but are blind, only detecting light.
Thaler also wants to let crash victims know to toss their clothes because "hagfishslime is so tough and dense that scientists are looking into using it to create a natural lycra". The slime, a type of mucus, in a hagfish can expand to more than five gallons when combined with water.
The Depoe Bay Fire Department helped with the cleanup, which had the highway back open by 4:30 p.m.
