2010 Interesting Animal Discoveries

As 2010 comes to a close, we thought it would be fun to take a look back at some of the amazing animal discoveries that came to light in the past year.

Israel’s “Lifting Door” Spider
With a leg span of 14 cm (5.5 in.), a new spider found in the dune of the Sands of Samar in Israel is the largest of its type in the Middle East. In addition, scientists have concluded that Cerbalus aravensis is a nocturnal spider that lives in an underground den with a “lifting door” made of glued sand particles so the den remains camouflaged.

Ecuador’s Scaly-Eyed Gecko

Recent exploration by U.S. and Ecuadorian researchers have found more than 30 new species of animals in Ecuador, including the scaly-eyed gecko. A full-grown scaly-eyed gecko is small enough to sit atop the eraser of a pencil. These geckos crawl along the forest floor, making them difficult to spot.

Dinosaurs’ True Colors

Two groups of researchers using electron microscope technology have determined the true colors of two species of dinosaurs.  Sinosauropteryx, a turkey-sized carnivorous dinosaur, had reddish-orange feathers and striped tail.  Anchiornis huxleyi, a chicken-sized dinosaur, had black and white wings and red crown – similar to some woodpeckers.

All-Black King Penguin

An extremely rare all-black penguin was photographed near Antartica by Andrew Evans of National Geographic.  The king penguin doesn’t look like his tuxedoed counterparts because of what one scientist described as a “one in a zillion kind of mutation.”

World’s Largest (and Toughest) Spider Web

A newly discovered spider in Madagascar builds the longest and largest orb webs in the world. The spider, called Darwin’s bark spider, builds webs over rivers that can measure up to 2.8 square meters (about 30 square feet)!  The webs are made of the toughest biomaterial yet discovered and can catch 30 or more insects at any given time.

Reclusive Loris Photographed

One of the most reclusive primates in the world, the Horton Plains slender loris, has only been spotted four times since 1937. So rare were sightings that researchers thought this loris had gone extinct sometime between sightings in 1939 and 2002.  As deforestation has led to a decline in all populations of slender loris, researchers made the effort this year to study the nocturnal primates in their native habitat in Sri Lanka and southern India.  This photo was taken as part of the study.

Giant Penguin Fossils

Scientists in Peru uncovered the fossils of a Water King, a giant 5-foot penguin that weighed twice as much as an emperor penguin (the world’s largest living penguin) and lived 36 million years ago.  The fossils, which included well-preserved feathers and scales, led scientists to determine that the Water King had brown and gray feathers, unlike the black and white feathers we associate with modern penguins, and it was a very strong swimmer and diver.
