In the depths of the ocean, a peculiar creature with hairy legs and red eyes may seem like a creature from a nightmare. However, these eerie beings are very real and have recently been identified as two new species in the Salish Sea region of southern British Columbia.
Researchers, led by Cormac Toller-Scott from the University of British Columbia, made this discovery during a marine exploration. Toller-Scott, pursuing his master’s degree in zoology, highlighted the lack of research on marine invertebrates in the area, especially sea spiders, which are ancient ocean-dwelling relatives of terrestrial spiders.
During dives conducted between September 2023 and August 2024, the team explored various marine habitats in locations such as Quadra Island, Vancouver, Bamfield, and Victoria. By meticulously analyzing physical characteristics and genetic data of collected specimens, they confirmed the existence of two previously undocumented sea spider species living on hydroids, organisms resembling attached jellyfish.
The newfound species were named “Callipallene pilosuspedes,” referencing its hairy-legged appearance, and “Tanystylum kiixin,” named after a nearby Indigenous village site. This discovery adds to the limited knowledge of sea spiders in the Salish Sea and Vancouver Island region, showcasing the importance of taxonomy in scientific research.
Despite the critical role taxonomic studies play in scientific progress, projects like this often face funding challenges. Toller-Scott emphasized the significance of taxonomy in laying the groundwork for broader scientific inquiries, suggesting that many more undiscovered species likely await exploration along the diverse coastline of Western Canada.
