Jump for joy: Blue frog babies

After five years of experimenting to create the perfect amorous am·o·rous

 atmosphere for their blue poison arrow frogs, scientists at the National Aquarium in Baltimore have something to celebrate: six newly metamorphosed blue frogs, the first bred in the United States. A rainbow of other-colored poison arrow frogs -- 50 black-and-green, 20 orange-striped and 21 yellow -- also were successfully hatched and metamorphosed from tadpoles Tadpoles are a psychedelic rock band formed in 1990 in New York City by Todd Parker (guitars/vocals) and Michael Kite Audino (drums.) In 1992, Nick Kramer (guitars/vocals), David Max (bass) and Andrew Jackson (guitars) of the fledgling Manhattan group, Hit, joined the Tadpoles  between July 1987 and February 1988. And two other species are in the tadpole tadpole, larval, aquatic stage of any of the amphibian animals. After hatching from the egg, the tadpole, sometimes called a polliwog, is gill-breathing and legless and propels itself by means of a tail.  stage.

The poison arrow frog family was recently given "threatened" status by the Convention on the International Trade of Endangered Species endangered species, any plant or animal species whose ability to survive and reproduce has been jeopardized by human activities. In 1999 the U.S. government, in accordance with the U.S. , which regulates the export and import of animals. The frogs' already limited habitat -- from Nicaragua to Bolivia and Brazil -- is being destroyed as rain forests are cleared for agriculture and ranching. Blue poison arrow frogs inhabit an even smaller area, living in isolated "forest islands" in the savanna savanna or savannah (both: səvăn`ə), tropical or subtropical grassland lying on the margin of the trade wind belts.  of southern Surinam, near the Brazil border. This region is not currently threatened, but scientists want to learn about the frogs' breeding as a hedge against future threats to their existence in the wild.

"One of the biggest reasons we have [for breeding the frogs] is to show the public that other living things besides just trees are going to be lost in rain forests when they're cleared," says herpetologist her·pe·tol·o·gy

. The researchers discovered the frogs prefer to live in pairs rather than in large groups and they require the privacy and security of a relatively small nest to lay and fertilize their eggs. Taking cues partly from European breeders, Cover and his colleagues made "breeding huts" out of the upside-down bottoms of 2-liter soda bottles, cutting a small door in each.

A more varied diet enriched in vitamins and minerals and an increase in humidity to simulate the rainy season also may have helped put the frogs in a steamy state of mind.
