Scientists have captured stunning video of a dinner-plate-size sea spider crawling on the seafloor off the South Sandwich Islands, a chain of volcanic islands near Antarctica in one of the most remote areas of the world.
Sea spiders, also known as pycnogonids, are distant cousins of the creepy-crawly arachnids we see scuttling about on land. These creatures can have leg spans of up to 20 inches (51 centimeters) — nearly double those of the largest land spiders, whose leg spans top out at around 12 inches (30 cm).
