The Prague Zoo has joined an international effort to ensure the survival of a rare insect that had been considered extinct for more than 80 years.
The zoo is among six institutions around the world that have been able to create living conditions for the largest species of flightless insect, the Lord Howe Island stick insect, which grows up to 15 centimeters (5.9 inches) long. They are on display, a rare chance that only London and San Diego also offer.
