New video reveals how blood work can be used to identify sick sea stars

A new video from Oregon Sea Grant (OSG), Sea Star Health: Using Blood Work to Identify Sick Sea Stars, reveals how OSG and Oregon State University created the first-ever blood panel for ochre sea stars to use as a baseline for detecting sick ones. The tool could help aquarists treat them before they succumb to Sea Star Wasting Syndrome, which causes their limbs to fall off.

The cause of the syndrome, which was first seen in the Pacific Northwest in 2013, is unknown. OSU veterinary student Heather Renee Srch-Thaden created the blood panel under the guidance of Dr. Tim Miller-Morgan, an aquatic veterinarian with OSG Extension, and Dr. Susan Tornquist, dean of OSU’s College of Veterinary Medicine.

The video was filmed at OSU’s Hatfield Marine Science Center in Newport, where the public can touch and learn about sea stars in a tidepool exhibit at the HMSC Visitor Center. It was filmed and edited by OSG videographer Vanessa Cholewczynski, with photos by Tim Miller-Morgan and Heather Renee Srch-Thaden.
