Starfish dying in alarming numbers

 
Sea stars dying in alarming numbers, some with limbs falling off and others apparently melting in place.

It appears like a contagion because it spreads to adjacent populations.

It’s normal for a sea star to drop an arm if a predator has a good hold on one arm. They just lop off an arm, like a lizard deliberately losing its tail so it can live to grow a new one.

But this is different.

A time-lapse video of a diseased sunflower sea star at the Vancouver Aquarium, quarantined in a hospital habitat, is a curious sight: Over the span of seven hours, the sea star moves throughout the tank, its arms falling off one by one and wiggling away.
