This week's science news was filled with things missing and found, with the revelation of the first-ever deep-sea footage of the elusive goblin shark making waves in the press.
Goblin sharks (Mitsukurina owstoni) are mysterious, deepwater creatures that have not changed much since they first appeared on Earth 125 million years ago — making them "living fossils." But capturing a recording of the sharks in their deep habitats is exceptionally difficult, and they have previously been seen alive only after being hooked to the surface on fishing lines. Scientists recently filmed not one, but two goblin sharks: The first near Jarvis Island in the South Central Pacific, and the second 6,550 feet (1,997 meters) deep in the Tonga Trench.
