‘Rock Vomit’ Causing Problems in Alaska [VIDEOS]
By the looks of it, you’d think a band of Alaskan creatures threw a rockin’ party and had a bit too much to drink.
That’s because an invasive species, nicknamed “rock vomit,” has infiltrated the state, covering plants, rocks, seashells, boats and any other hard surface with a substance eerily similar to puke.
The species is technically referred to as the “Didemnum vexillum” and is a variety of sea squirt that was discovered in Alaska last June. It adheres itself to a hard surface and continues spreading.
Though unsightly, the main problem with rock vomit is that it prevents ground fish from reaching their food and can be lethal to other creatures, including commercially sold fish. New England, California, Oregon and Washington are also dealing with the infestation.
