Working Dog Honored as Animal of the Year for Combating Invasive Sea Squirt

A working dog named Sgiath has been recognized as "Animal of the Year" for her crucial role in detecting an invasive marine species known as the carpet sea squirt. The black Labrador's advanced scent detection skills are proving instrumental in conservation efforts against this harmful organism.

Dr. Sim, who led the project, expressed surprise at the success of the initiative, stating, "When I first started this project, I genuinely didn't know whether it would work." She added that the exploration of canine assistance in tackling marine environmental issues was a novel concept that has exceeded expectations.

Dogs are commonly employed in land-based conservation for tracking endangered species and investigating environmental crimes. Sgiath's unique approach involves surveying coastlines at low tide, pinpointing the location of the carpet sea squirt by scent "under the seaweed."

The carpet sea squirt, scientifically named Didemnum vexillum, is believed to have originated from Japan and first appeared on the shores of southern England and Wales in 2008. This fast-reproducing species, which can vary in color from orange to cream, has since spread to numerous coastal areas in the UK.

Marine biologists are concerned that warming seas could facilitate the further spread of the carpet sea squirt. Dr. Martyn Kurr, a marine biologist from Bangor University, explained that non-native species like the carpet sea squirt, often referred to as "biofouling" organisms, can outcompete native wildlife for essential nutrients. He also noted that these species can obstruct aquaculture pens, marine infrastructure, and equipment such as boat propellers.

The economic impact of these invasive species is significant, with millions of pounds spent annually across Europe on control and cleanup efforts. Sgiath's work represents a novel and effective method in the ongoing battle against marine invaders.
