Scientists Discover Two Weird New Sea Spiders

Topic: Biology

Researchers at the University of British Columbia found two new species of sea spiders in the Salish Sea. The discoveries are significant because they help scientists understand these unusual marine animals better.

Scientists have discovered two bizarre new sea spider species in the Salish Sea, off the coast of Canada. The discovery was made by researchers at the University of British Columbia.

The team collected specimens between September 2023 and August 2024 during dives reaching depths of up to 18 meters. They found one specimen with hairy legs and striking red eyes, which they named Callipallene pilosuspedes. The name is a reference to the Latin words for 'hairy feet'.

The second species, Tanystylum kiixin, takes its name from an ancient Indigenous village site near the location where specimens were found.

Sea spiders are ancient animals that belong to a lineage that arose roughly 500 million years ago. They are related to spiders, scorpions, and horseshoe crabs, but unlike their land-dwelling relatives, they remained entirely marine.

The researchers used detailed physical observations and genetic analysis to help fill major gaps in scientists' understanding of these unusual marine animals.

Why It Matters

This discovery is important because it helps us understand the diversity of life on our planet. It also highlights the impact of climate change and human disturbance on marine ecosystems, which are particularly at-risk.
