A rare frilled shark was captured live by fishermen off the coast of Japan. The toothy eel-like creature was taken to Awashima Marine Park in Shizuoka where it later died, according to Reuters.
The 5-foot (1.6 meter) long beast was believed to be ill because it was found in shallow waters. Generally the species, known as Chlamydoselachus anguineus, lives at a depth of 488-4550 feet (150-1400 m) in the Atlantic and Pacific Oceans.
“We believe moving pictures of a live specimen are extremely rare,” Reuters quoted an official at the park as saying. “They live between 600 and 1000 meters under the water, which is deeper than humans can go. We think it may have come close to the surface because it was sick, or else it was weakened because it was in shallow waters.”
The frilled shark is considered a primitive shark, largely unchanged since prehistoric times. The species’ unusual appearance has led some to suggest that it could be a source for sea serpent sightings.
Frilled sharks are occasionally captured as bycatch, but they are not targeted commercially. Nonetheless, the IUCN considers the species “near threatened” due to its slow reproductive rate — its gestation period is thought to be up to 42 months — and expansion of industrial deep-water fishing.

Amazon natives use Google Earth, GPS to protect rainforest home. Deep in the most remote jungles of South America, Amazon Indians (Amerindians) are using Google Earth, Global Positioning System (GPS) mapping, and other technologies to protect their fast-dwindling home. Tribes in Suriname, Brazil, and Colombia are combining their traditional knowledge of the rainforest with Western technology to conserve forests and maintain ties to their history and cultural traditions, which include profound knowledge of the forest ecosystem and medicinal plants. Helping them is the Amazon Conservation Team (ACT), a nonprofit organization working with indigenous people to conserve biodiversity, health, and culture in South American rainforests.
