Researchers at the Monterey Bay Aquarium Research Institute (MBARI) captured this image of a barreleye fish (Macropinna microstoma) in the deep waters just offshore of Central California from a video taken by a remotely operated video at depths of 2,000 to 2,600 feet. Since it was discovered in 1939, the barreleye's vision has been a mystery, until scientists at MBARI solved it on Feb. 23, 2009. The barreleye has extremely light-sensitive, tubular eyes that can rotate inside of its transparent head. Capped by bright green lenses, the fish's eyes point upward when it looks for food overhead, and then they point forward when the fish is feeding to focus on its prey.

For the first time since 1921, scientists observed a living pygmy tarsier -- one of the planet's smallest and rarest primates -- on the Indonesian island of Sulawesi. Some scientists believed the tarsiers had become extinct because they had not been seen for so long. The nocturnal animals are very small -- weighing 2 ounces -- and have large eyes and ears.

An Axolotl salamander, or Ambystoma mexicanum, swims in a tank at the Chapultepec Zoo in Mexico City. Scientists warn that the roughly foot-long amphibian is a few years away from extinction, a victim of the draining of its lake habitat, deteriorating water quality and what is perhaps the final stake in its heart: the invasion of nonnative fish species that eat its eggs and larvae, and compete with it for food.

Two conjoined Nile tilapia fish, dubbed "Siamese twin," swim in a small aquarium in Bangkok, Thailand, Oct. 3, 2008. They are both 8 months old and share part of their skin. The bigger fish tends to protect the smaller one from harm while the smaller one looks for food at the bottom of the aquarium.

The African okapi is so elusive it was once believed to be a mythical unicorn. This okapi - seen in Virunga National Park in the Democratic Republic of the Congo -- is the first one photographed in the wild, the Zoological Society of London said Thursday. Its appearance proves that the species is still surviving despite more than a decade of civil conflict. Zoologists found evidence of an okapi population in the park through tracks a few years ago. Experts say the photos indicate a second group also exists there. The animal previously had only been glimpsed in passing in the wild, but captive okapis are found in many zoos Okapi have characteristics similar to deer and giraffes but are most notable for their zebra-like leg stripes.
