Squid? Worm? Initially, this new species—with bristle-based “paddles” for swimming and tentacles on its head—so perplexed Census of Marine Life researchers that they threw in the towel and simply called it squidworm, National Geographic News reported in November.
Found via remotely operated vehicle about 1.7 miles (2.8 kilometers) under the Celebes Sea (see map) in 2007, the four-inch-long (ten-centimeter-long) creature turned out to be the first member of a new family in the Polychaeta class of segmented worms.
