By duration · Order from shortest to longest.

1. A chameleon's tongue reaching its insect prey 72 ms

   Small chameleons have the fastest tongues, accelerating at hundreds of g — proportionally the most powerful movement of any reptile, bird, or mammal.

2. Yuri Gagarin's entire Vostok 1 spaceflight 108 min

   The first human spaceflight was a single orbit — and Gagarin ejected and parachuted down separately from his capsule, landing in a potato field.

3. A Eurostar train journey from London to Paris 2.3 h

   Only about 20 minutes of the trip is actually under the sea — the Channel Tunnel remains the longest undersea rail tunnel in the world.

4. Rio de Janeiro's Carnival, official festival period 5 days

   Around two million people hit the streets per day, and the samba school parade is a fierce contest judged on dozens of criteria.

5. A periodical cicada's life cycle, egg to final emergence 17 years

   They spend 17 years underground and mere weeks in the sun — the prime-numbered cycle may have evolved to dodge predators' breeding rhythms.

6. One orbit of Pluto around the Sun 247.9 years

   Pluto hasn't completed a single orbit since its discovery in 1930 — it won't finish its first 'observed year' until 2178.
