Baby starfish are back!
Lexile

Droves of baby starfish are returning to Oregon and Northern California's shores.  A wasting disease destroyed 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 a record number of baby starfish. They also are called sea stars. They survived the summer and winter of 2015. This was reported by the Eureka Times Standard newspaper.
 
"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. It caused them to lose their limbs. Eventually they would break down 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. It 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 gone down in intensity. But he said it remains present.
 
Experts say it's encouraging to see the large number of baby starfish. But they believe disease, competition and environmental factors make survival of the starfish difficult.

    We don't know what was killing the starfish because there is no direct evidence to prove any of the hypothesis are correct. I think it is sad that millions of sea stars and dying without a known cause so there is no way to prevent it. I think it is interesting that they are starting to come back again and it is cool that it will affect us because we live on the coast of California.

    its really cool how they came back. i wonder how they came back? its sad how a virus went throughout the sea or ocean! i wonder why other animals in the sea were not affected by the disase. But i enjoyed lesnring new this about baby starfish.

    We dont know because they would be at the bottom of the ocean dead for awhile and all the evidence was washed away.

    I think it is sad that baby starfish and adult starfish are getting a disease that turns them into slime. It's just plain sad because what if we turned into slime? That would be sad an d scary. So put yourself in a starfish's shoes, would you like to turn to slime? Not living slime? Think about it.

    Me and my sister both collect things, she collects starfish and I collect snow globes. When I go to Florida this summer I will get her starfish!

    I love collecting sea stars or star fish, me and my sister collect snow globes and sea stars!
