Despite being separated by a distance of 7,000 miles, this ribbon worm species in the Arctic is identical to a ribbon worm species found in the Antarctic. Scientists at the Census for Marine Life were surprised to find as many as 235 species that live in both polar seas.
This one, Pelagonemertes rollestoni
, measures about 1.2 incles long. It's got a dart attached to its tongue, which it uses to harpoon zooplankton. Its yellow stomach reaches out to feed all parts of its body.
