Sea star wasting disease

Sea Star Wasting Disease is a disease that affects starfish and has been linked to significant declines in starfish populations in the Pacific Ocean. The disease is characterized by lesions, followed by decay and fragmentation of the body, leading to death. The cause of the disease is still under investigation, but it is believed to be associated with a densovirus.

Symptoms

The first signs of Sea Star Wasting Disease are white lesions appearing on the starfish's body. These lesions spread rapidly, leading to the decay of tissue and the fragmentation of the body. The starfish eventually dies as a result of the disease.

Causes

The exact cause of Sea Star Wasting Disease is still under investigation. However, it is believed to be associated with a densovirus. This virus has been found in higher concentrations in starfish populations affected by the disease.

Impact

Sea Star Wasting Disease has had a significant impact on starfish populations in the Pacific Ocean. It has been linked to mass die-offs of starfish, leading to declines in their populations. This has had knock-on effects on the ecosystems in which starfish play a key role.

Research

Research into Sea Star Wasting Disease is ongoing. Scientists are working to understand the exact cause of the disease and how it spreads. They are also investigating potential treatments and ways to prevent the disease from spreading further.
