Sea Star (Pisaster ochraceus) appears sick but is actually healthy.
Observation by David Harmes:
Starfish has hundreds of pinholes.
Melissa Miner from University of California, Santa Cruz writes:
This star (Pisaster ochraceus) looks healthy to me! The "holes" described are simply a result of the interstitial fluid draining out of the top portion of the star. If you look at the lower half, it looks perfectly "plump" and healthy. This is a normal occurrence at low tide, but can give the appearance of something being wrong with the star.

Comments from LEO Editors:
Although this is an example of a healthy sea star, some species of sea star around Alaska are affected by Sea Star Wasting Syndrome. According to the Morro Bay Estuary Program, Sea Star Wasting Syndrome is a series of symptoms that lead to mortality. Typically, sea stars will develop lesions that eventually become surrounded with decay, causing a fragmentation of the sea star's body and eventual death. The Multi-Agency Rocky Intertidal Network (MARINe) is working to survey the Pacific Coast from Mexico to Alaska, tracking the progression of the disease through 200 monitoring sites. Several observations of Sea Star Wasting Syndrome have been submitted from the Kodiak Island area, pictured in the map below. Erica Lujan
