Cute Frog of the Week: April 2, 2012

The fringe-limbed tree frog is an extremely rare find, and therefore not much is known about this elusive species. These frogs live high in the canopy and are often overlooked. For this reason, it is difficult to conduct proper population counts, though they are considered endangered.

The prominent feature of these frogs is the dermal fringes between their fingers and toes. Scientists believe that this webbing can act like a parachute or glider wings when the frogs extend their fingers and toes outward, which would allow them to do just that— hop and glide from tree limb to tree limb. However, though this behavior has been observed in other related species, these particular guys have never been seen doing so. The frogs also have sticky disks at the tips of their fingers.

Based on individuals that have been found, this species’ coloration can range from lavender-brown, yellowish-white, brownish-tan, to green.

Native to Costa Rica and Panama, these frogs are nocturnal and from what researchers currently know, prefer living in humid premontane and lower montane forests. Being that these frogs spend most of their lives in the upper canopy, breeding, egg-laying and juvenile development occurs in tree-holes.

The main threats to these frogs are general habitat loss due to deforestation primarily for development and livestock ranching.

Cute Frog of the Week: December 19, 2011

The beautiful fringe-limbed tree frog is named for the small amount of whitish, fleshy fringe along the edges of its lower arms, hands, legs and feet. However, it is most memorable for its distinct colors—a deep blueish-green covered with many raised, yellowish-white spots. Their skin is also somewhat transparent, and their bones appear greenish through their skin. The fringe-limbed tree frog does not start out this beautiful, however. As if having to grow into their colors, the tadpoles, with their very long tails, are pale in color.

Because of this frog’s particularly long snout, its eyes are completely visible from the front of its head, unlike some other frogs, whose eyes can only be seen from the side. The specific name, euknemos, derives from Greek and means “with beautiful legs.” The male mating call sounds like a rapidly repeated “creep, creep, creep.”

These frogs can be found in humid Central and South American forests. They are more abundant in Columbia, but rare in Costa Rica and Panama because of deforestation.
