In the depths of the ocean, a peculiar creature resembling a monstrous dream visitor has been found – a sea spider with hairy legs and red eyes. Surprisingly, these eerie beings are real and not just a figment of imagination. Recently, researchers uncovered two new species of these sea spiders in the Salish Sea region of southern British Columbia.
Cormac Toller-Scott, a graduate student in zoology at the University of British Columbia, led the study on these mysterious sea spiders. He highlighted the lack of research on marine invertebrates in the area, particularly sea spiders, which are ancient relatives of terrestrial spiders that never left the oceans.
The research team, including Toller-Scott, conducted dives in various marine habitats in the region between September 2023 and August 2024, exploring depths of up to 18 meters. Their meticulous study involved collecting different species, analyzing fine physical characteristics, and comparing genetic data with known sea spider species worldwide.
Through their thorough examination, the team identified two previously undocumented sea spider species living on a hydroid, a stationary underwater organism resembling a grounded jellyfish. These sea spiders, considered parasites of the hydroid, feed on it by consuming small pieces with their proboscis as they wander around.
The newfound species were named Callipallene pilosuspedes, inspired by their hairy-legged appearance, and Tanystylum kiixin, named after a nearby Indigenous village site. This discovery adds to the growing knowledge of sea spider diversity, following a previous finding of methane-seep and hydrothermal-vent-dwelling sea spiders by another UBC research team.
Despite the importance of taxonomic research projects like this one, Toller-Scott noted the lack of funding for such endeavors. He emphasized the significance of taxonomy in laying the groundwork for broader scientific inquiries and highlighted the vast potential for discovering new species, particularly along the diverse coastlines of the Canadian West Coast.
