Baby starfish are back!
Lexile

Droves of baby starfish are returning to Oregon and Northern California's shores.  A wasting disease decimated whole populations of the creatures. This occurred over the past two years along the West Coast.
 
Data was collected by Oregon State University researchers. The research shows an unprecedented number of baby starfish, or sea stars. They survived the summer and winter of 2015. The story was reported by the Eureka Times Standard.
 
"When we looked at the settlement of the larval sea stars on rocks in 2014 during the epidemic, it was the same or maybe even a bit lower than previous years," Oregon State University marine biology professor Bruce Menge said in a statement.
 
But a few months later, the number of juveniles was off the charts. It was "higher than we'd ever seen. As much as 300 times normal."
 
A similar increase was found at sites just north of Trinidad, California. That is near Patrick's Point State Park. A baby starfish boom also was noted in the summer of 2014. It was near Santa Cruz.
 
A virus killed millions of starfish on the Pacific Coast from Southern California to Alaska by causing them to lose their limbs. Eventually they would disintegrate into slime and piles of tiny bones.
 
The cause of the outbreak remains unclear. Some have hypothesized it to be abnormally warm waters in the Pacific Ocean. The warmer waters have wreaked havoc on marine ecosystems. This has been going on for the past two years.
 
Humboldt State University Marine Lab Director Brian Tissot disagrees with that hypothesis. That is because the virus spread during colder months and didn't expand as much during the abnormally warm 2015.
 
"There is no clear environmental cue," Tissot said. He added the deadly wasting disease has declined in intensity. But he said it remains present.
 
Experts say that while it's encouraging to see the abundance of baby starfish, the disease, competition and environmental factors make their survival difficult.

    Yay, I'm glad to know that starfish might not go endangered or extinct soon. I also didn't know that the disease make the starfish disintegrate.

      I agree. I am so happy that starfish might not go endangered or extinct. I find it interesting that the disease make starfish disintergrate. What in the disease makes the starfish disintegrate?

    Researchers have not yet figured out what is killing star fish, so we have no clear idea yet as to what it might be that is causing it.

    Researchers don't have enough evidence to determine what was killing all the starfish so they can't find a way to help against this starfish killing.

    There is no clear environmental cue so scientists do not know what caused it.

    wow I thought they were never gone but something is killing star fish but nobody knows what animal is killing these amazing creatures we must find out what animal is responsible.

    The researchers can't figured out what happened to the starfish so they cant help or stop what is killing them.

    We don't know what is killing the starfish because a waste disease killed most of the starfish's population.But in 2015 the starfish has survived the hot days in summer, and survived in the cold days in summer.

    We also has no proved evident's on what is causing the starfish's to die.

    If people thought this species was extinct and they came back, I wonder what else could come back. Maybe stuff like dinosaurs could make a comeback. Who knows! The ocean is so vast maybe there are aquatic dinosaurs living among us right now!

    We do not know what was killing the starfish because we are not out in then ocean and we can not see what is going on out there. The article states that "There is no clear environmental cue," this means that we do not know for sure what is causing the death of the starfish. This means that there is not clue, regarding the environment that shows what was killing the starfish. This could indicate that what is killing the starfish is not an environmental issue but an issue that is caused by us, the human population and we can do something about the starfish dying.
