The team traveled to Haiti in search of this frog, but were not able to track it down. It was last seen in 1985.

This rare species, last seen in 1991, was the first of the six lost frogs found by the team. It was named for a subtle row of bumps that look like a crown on the back of its head. "Fewer than 10 individuals of this frog have ever been found," says Moore. "It was very exciting to find it on this trip. We found it on the first day of searching, so we started well!" 

Last seen in 1991, this "ventriloquist" frog has the ability to project its call to sound as if it is coming from somewhere else. That made it difficult for the team to find it. "We spent about an hour and a half on the first night searching for this frog without any success, even though we could hear it calling," Moore says. "But we were determined to find it. We returned the following night, and it took hours (perhaps three total) to eventually find it."

Discovered by Hedges, this musical frog was named after composer Wolfgang Amadeus Mozart. Its call is a four-note muffled whistle at night. At dawn and dusk, the call is usually given as a shorter, two-note whistle. It was last seen in 1991.

This juvenile Macaya breast-spot frog climbed onto a tent that the expedition team had pitched in a clearing in the cloud forest. "I turned out that the frogs liked climbing on our tents," Moore told TFK. "It made finding very tiny ones such as the Macaya breast-spot frog possible. This is the smallest frog I have ever seen, and I had to capture a photo that showed it's size." When fully grown, the frog is about the size of a green grape. It was last seen in 1991.

This frog is known for its striking, sapphire-blue eyes, which is a very unusual trait among amphibians. It was last seen in 1991.

This was a surprising find because the species had never been seen before in the area the team was searching. "Only when Blair Hedges did some genetic tests following the expedition did we realize that it was, in fact, one of the lost frogs," Moore explains. The frog has big, jet-black eyes and bright orange flashes on its legs. It was last seen 1996. 

A cloud forest in Macaya Biosphere Reserve on the Massif de la Hotte mountains, in southwest Haiti. The country's shrinking cloud forests are home to many critically endangered amphibians. Rampant deforestation has left only about 1% of Haiti's original forest cover in tact. "If we can protect these forests, it will have many benefits for people in Haiti for decades to come," says Moore.
