Sick and dying starfish (sea stars) have appeared in a multitude of locations between Alaska and southern California.
"It's like a zombie wasteland," says biologist Emily Tucker told Nature. "You'll see detached arms crawling away from their body."
Called Sea Star Wasting Disease, it can cause the death of an infected starfish in just a few days. Its effects can be devastating on starfish populations.
The disease has hit before, in southern California in 1983-1984 for example and again in 1997-98. These events were associated with warmer sea temperatures. The current outbreak is more widespread.
It is particularly worrying because one of the starfish affected, Pisaster ochraceus, was the original "keystone species". This is a species that has a disproportionately large effect on its environment relative to its abundance. Without it the ecosystem would be dramatically different. The concept was first proposed in 1969 usingPisaster ochraceus as a primary example. Within a year of Pisaster ochraceus being removed, biodiversity halved.
Lesions on the animal are the first signs of the disease. Tissue then decays around the lesions which leads to break up of the body and death.

We are in Newfoundland on a 10-day adventure that will take us snorkeling with whales, scuba diving on World War II wrecks, hiking along the East Coast Trail, and canoeing and fishing in the Terra Nova National Park.
“This fall, Roane State associate professor of biology Bruce Cantrell and adjunct instructor Jessica Fain plan to live and work under the sea for 72 days. While underwater, Cantrell and Fain will offer the most unique educational experience in the college's history and raise awareness of issues affecting the oceans. They will host a weekly program featuring interviews with leading scientists and explorers, covering topics such as conservation, undersea exploration and more. Roane State students in Cantrell's fall online biology class will have an especially interesting experience; while they take the course online, their professor will be leading it from the floor of the lagoon at the Marine Resources Development Foundation's facilities in Key Largo, Fla.”
“Where Bruce and Jessica Will Live?
“Bruce and Jessica will stay in Jules' Undersea Lodge. Located 21 feet below the surface of the sea at the Marine Resources Development Foundation, the underwater habitat features a wet room, two bedrooms and a common room. For safety, the facility is monitored at all times.”
It should be noted that while they are conducting research and educational outreach, they will also be challenging a long standing world record, currently held by Rick Presley, who in 1992 stayed in an undersea Laboratory (at ambient pressure) for 69 days and 19 minutes. Again, the planned stay for Bruce Cantrell and Jessica Fain is planned for 72 days. For more information please visit their website at…: http://www.roanestate.edu/classroomunderthesea/
